6 56f8356 technical data preliminary the 56f8356 supports program execution from either internal or external memories. two data operands can be accessed from the on-chip data ram per instruction cycle. the 56f8356 also provides two external dedicated interrupt lines and up to 62 general purpose input/output (gpio) lines, depending on peripheral configuration. the 56f8356 hybrid controller includes 256kb of program flash and 8kb of data flash (each programmable through the jtag port) with 4kb of program ram and 16kb of data ram. it also supports program execution from external memory. a total of 16kb of boot flash is incorporated for easy customer-inclusion of field-programmable software routines that can be used to program the main program and data flash memory areas. both program and data flash memories can be independently bulk erased or erased in pages. program flash page erase size is 1kb. boot and data flash page erase size is 512 bytes. the boot flash memory can also be either bulk or page erased. a key application-specific feature of the 56f8356 is the inclusion of two pulse width modulator (pwm) modules. these modules each incorporate three complementary, individually programmable pwm signal output pairs (each module is also capable of supporting six independent pwm functions, for a total of 12 pwm outputs) to enhance motor control functionality. complementary operation permits programmable dead time insertion, distortion correction via current sensing by software, and separate top and bottom output polarity control. the up-counter value is programmable to support a continuously variable pwm frequency. edge-aligned and center-aligned synchronous pulse width control (0% to 100% modulation) is supported. the device is capable of controlling most motor types: acim (ac induction motors); both bdc and bldc (brush and brushless dc motors); srm and vrm (switched and variable reluctance motors); and stepper motors. the pwms incorporate fault protection and cycle-by-cycle current limiting with sufficient output drive capability to directly drive standard optoisolators. a smoke-inhibit, write-once protection feature for key parameters is also included. a patented pwm waveform distortion correction circuit is also provided. each pwm is double-buffered and includes interrupt controls to permit integral reload rates to be programmable from 1 to 16. the pwm modules provide reference outputs to synchronize the analog-to-digital converters through two channels of quad timer c. the 56f8356 incorporates two quadrature decoders capable of capturing all four transitions on the two-phase inputs, permitting generation of a number proportional to actual position. speed computation capabilities accommodate both fast- and slow-moving shafts. an integrated watchdog timer in the quadrature decoder can be programmed with a time-out value to alert when no shaft motion is detected. each input is filtered to ensure only true transitions are recorded. this hybrid controller also provides a full set of standard programmable peripherals that include two serial communications interfaces (scis); two serial peripheral interfaces (spis); and four quad timers. any of these interfaces can be used as general purpose input/outputs (gpios) if that function is not required. a flex controller area network (flexcan) interface (can version 2.0 b-compliant) and an internal interrupt controller are a part of the 56f8356. f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .
award-winning development environment 56f8356 technical data 7 preliminary 1.3 award-winning development environment processor expert tm (pe) provides a rapid application design (rad) tool that combines easy-to-use component-based software application creation with an expert knowledge system. the codewarrior integrated development environment is a sophisticated tool for code navigation, compiling, and debugging. a complete set of evaluation modules (evms) and development system cards will support concurrent engineering. together, pe, codewarrior and evms create a complete, scalable tools solution for easy, fast, and efficient development. 1.4 architecture block diagram the 56f8356 architecture is shown in figure 1-1 and figure 1-2 . figure 1-1 illustrates how the 56800e system buses communicate with internal memories, the external memory interface and the ipbus bridge. table 1-1 lists the internal buses in the 56800e architecture and provides a brief description of their function. figure 1-2 shows the peripherals and control blocks connected to the ipbus bridge. the figures do not show the on-board regulator and power and ground signals. they also do not show the multiplexing between peripherals or the dedicated gpios. please see part 2, signal/connection descriptions, to see which signals are multiplexed with those of other peripherals. also shown in figure 1-2 are connections between the pwm, timer c and adc blocks. these connections allow the pwm and/or timer c to control the timing of the start of adc conversions. the timer c channel indicated can generate periodic start (sync) signals to the adc to start its conversions. in another operating mode, the pwm load interrupt (sync output) signal is routed internally to the timer c input channel as indicated. the timer can then be used to introduce a controllable delay before generating its output signal. the timer output then triggers the adc. to fully understand this interaction, please see the 56f8300 peripheral user manual for clarification on the operation of all three of these peripherals. f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .

program map 56f8356 technical data 35 preliminary 4.2 program map the operating mode control bits (ma and mb) in the operating mode register (omr) control the program memory map. at reset, these bits are set as indicated in table 4-2 . table 4-4 shows the memory map configurations that are possible at reset. after reset, the omr ma bit can be changed and will have an effect on the p-space memory map, as shown in table 4-3 . changing the omr mb bit will have no effect. the 56f8356s external memory interface (emi) can operate much like the 56f80x familys emi, or it can be operated in a mode similar to that used on other products in the 56800e family. initially, cs0 and cs1 are configured as ps and ds , in a mode compatible with earlier 56800 devices. eighteen address lines are required to shadow the first 192k of internal program space when booting externally for development purposes. therefore, the entire complement of on-chip memory cannot be accessed using a 16-bit 56800-compatible address bus. to address this situation, the emi_mode pin can be used to configure four gpio pins as address[19:16] upon reset (only one of these pins [a16] is usable in the 56f8356). the emi_mode pin also affects the reset vector address, as provided in table 4-4 . additional pins must be configured as address or chip select signals to access addresses at p:$10 0000 and above. table 4-2 omr mb/mal value at reset omr mb = flash secured state 1, 2 1. this bit is only configured at reset. if the flash secured state changes, this will not be reflected in mb until the next res et. 2. changing mb in software will not affect flash memory security. omr ma = extboot pin chip operating mode 0 0 mode 0 C internal boot; emi is configured to use 16 address lines; flash memory is secured; external p-space is not allowed; the eonce is disabled 0 1 not valid; cannot boot externally if the flash is secured and will actually configure to 00 state 1 0 mode 0 C internal boot; emi is configured to use 16 address lines 1 1 mode 1 C external boot; flash memory is not secured; emi configuration is determined by the state of the emi_mode pin table 4-3 changing omr ma value during normal operation omr ma chip operating mode 0 use internal p-space memory map configuration 1 use external p-space memory map configuration C if mb = 0 at reset, changing this bit has no effect. f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .
36 56f8356 technical data preliminary 4.3 interrupt vector table table 4-5 provides the reset and interrupt priority structure, including on-chip peripherals. the table is organized with higher-priority vectors at the top and lower-priority interrupts lower in the table. the priority of an interrupt can be assigned to different levels, as indicated, allowing some control over interrupt priorities. all level 3 interrupts will be serviced before level 2, and so on. for a selected priority level, the lowest vector number has the highest priority. the location of the vector table is determined by the vector base address (vba) register. please see section 5.6.12 for the reset value of the vba. in some configurations, the reset address and cop reset address will correspond to vector 0 and 1 of the interrupt vector table. in these instances, the first two locations in the vector table must contain branch or jmp instructions. all other entries must contain jsr instructions. table 4-4 program memory map at reset begin/end address mode 0 (ma = 0) mode 1 1 (ma = 1) 1. if flash security mode is enabled, extboot mode 1 cannot be used. see security features, part 7 . internal boot external boot internal boot 16-bit external address bus emi_mode = 0 2 , 3 16-bit external address bus 2. this mode provides maximum compatibility with 56f80x parts while operating externally. 3. emi_mode =0 when emi_mode pin is tied to ground at boot up. emi_mode = 1 4 20-bit external address bus 4. emi_mode =1 when emi_mode pin is tied to v dd at boot up. p:$1f ffff p:$10 0000 external program memory 5 5. not accessible in reset configuration, since the address is above p:$00 ffff. the higher bit address/gpio (and/or chip selects) pins must be reconfigured before this external memory is accessible. external program memory 5 external program memory 5 p:$0f ffff p:$03 0000 external program ram cop reset address = 02 0002 6 boot location = 02 0000 6 6. booting from this external address allows prototyping of the internal boot flash. p:$02 ffff p:$02 f800 on-chip program ram 4kb p:$02 f7ff p:$02 2000 reserved 116kb p:$02 1fff p:$02 0000 boot flash 16kb cop reset address = 02 0002 boot location = 02 0000 boot flash 16kb (not used for boot in this mode) p:$01 ffff p:$01 0000 internal program flash 7 128kb 7. two independent program flash blocks allow one to be programmed/erased while executing from another. each block must have its own mass erase. internal program flash 128kb p:$00 ffff p:$00 0000 internal program flash 7 128kb external program ram cop reset address = 00 0002 boot location = 00 0000 f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .

40 56f8356 technical data preliminary 4.5 flash memory map figure 4-1 illustrates the flash memory (fm) map on the system bus. the flash memory is divided into three functional blocks. the program and boot memories reside on the program memory buses. they are controlled by one set of banked registers. data memory flash resides on the data memory buses and is controlled separately by its own set of banked registers. the top nine words of the program memory flash are treated as special memory locations. the content of these words is used to control the operation of the flash controller. because these words are part of the flash memory content, their state is maintained during power-down and reset. during chip initialization, the content of these memory locations is loaded into flash memory control registers, detailed in the flash memory chapter of the 56f8300 peripheral user manual . in the 56f8356, these configuration parameters are located between $01_fff7 and $01_ffff. figure 4-1 flash array memory maps table 4-7 shows the page and sector sizes used within each flash memory block on the chip. please see 56f8300 peripheral user manual for additional flash information. table 4-7. flash memory partitions flash size sectors sector size page size program flash 256kb 16 8k x 16 bits 512 x 16 bits data flash 8kb 16 256 x 16 bits 256 x 16 bits boot flash 16kb 4 2k x 16 bits 256 x 16 bits prog_flash_start + $01_ffff prog_flash_start + $01_fff7 prog_flash_start + $01_fff6 prog_flash_start + $01_0000 prog_flash_start + $00_ffff prog_flash_start = $00_0000 data memory data_flash_start + $0fff data_flash_start + $0000 fm_base + $14 fm_base + $00 boot_flash_start + $1fff boot_flash_start = $20_0000 fm_prog_mem_top = $01_ffff block 0 odd (2 bytes) $00_0003 block 0 even (2 bytes) $00_0002 block 0 odd (2 bytes) $00_0001 block 0 even (2 bytes) $00_0000 block 1 odd (2 bytes) $01_0003 block 1 even (2 bytes) $01_0002 block 1 odd (2 bytes) $01_0001 block 1 even (2 bytes) $01_0000 program memory 16kb boot 128kb program configure field 128kb program banked registers unbanked registers 8kb f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .

factory programmed memory 56f8356 technical data 67 preliminary 4.8 factory programmed memory during manufacturing the boot flash memory block is programmed with a default serial boot- loader program. the serial bootloader application can be used to load a user application into the program and data flash memories of the device. the document mc56f83xxblum/d, 56f83xx sci/can bootloader user manual provides detailed information on this firmware. the appli- cation note an1973/d, production flash programming provides additional information on how the serial bootloader program can be used to perform production flash programming of the on board flash memories as well as other potential methods. like all the flash memory blocks the boot flash can be erased and programmed by the user. the serial bootloader application is programmed as an aid to the end user, but is not required to be used or maintained in the boot flash memory. f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .
68 56f8356 technical data preliminary part 5 interrupt controller (itcn) 5.1 introduction the interrupt controller (itcn) module is used to arbitrate between various interrupt requests (irqs), to signal to the 56800e core when an interrupt of sufficient priority exists, and to what address to jump in order to service this interrupt. 5.2 features the itcn module design includes these distinctive features: ? programmable priority levels for each irq ? two programmable fast interrupts ? notification to sim module to restart clocks out of wait and stop modes ? drives initial address on the address bus after reset for further information, see table 4-5 , interrupt vector table contents. 5.3 functional description the interrupt controller is a slave on the ipbus. it contains registers allowing each of the 82 interrupt sources to be set to one of four priority levels, excluding certain interrupts of fixed priority. next, all of the interrupt requests of a given level are priority encoded to determine the lowest numerical value of the active interrupt requests for that level. within a given priority level, zero is the highest priority, while number 81 is the lowest. 5.3.1 normal interrupt handling once the itcn has determined that an interrupt is to be serviced and which interrupt has the highest priority, an interrupt vector address is generated. normal interrupt handling concatenates the vba and the vector number to determine the vector address. in this way, an offset is generated into the vector table for each interrupt. 5.3.2 interrupt nesting interrupt exceptions may be nested to allow an irq of higher priority than the current exception to be serviced. the following tables define the nesting requirements for each priority level. table 5-1 interrupt mask bit definition sr[9] 1 1. core status register bits indicating current interrupt mask within the core. sr[8] 1 permitted exceptions masked exceptions 0 0 priorities 0, 1, 2, 3 none 0 1 priorities 1, 2, 3 priority 0 1 0 priorities 2, 3 priorities 0, 1 1 1 priority 3 priorities 0, 1, 2 f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .
functional description 56f8356 technical data 69 preliminary 5.3.3 fast interrupt handling fast interrupts are described in the dsp56800e reference manual . the interrupt controller recognizes fast interrupts before the core does. a fast interrupt is defined (to the itcn) by: 1. setting the priority of the interrupt as level 2, with the appropriate field in the ipr registers 2. setting the fimn register to the appropriate vector number 3. setting the fivaln and fivahn registers with the address of the code for the fast interrupt when an interrupt occurs, its vector number is compared with the fim0 and fim1 register values. if a match occurs, and it is a level 2 interrupt, the itcn handles it as a fast interrupt. the itcn takes the vector address from the appropriate fivaln and fivahn registers, instead of generating an address that is an offset from the vba. the core then fetches the instruction from the indicated vector adddress and if it is not a jsr, the core starts its fast interrupt handling. table 5-2 interrupt priority encoding ipic_level[1:0] 1 1. see ipic field definition in section 5.6.30.2 current interrupt priority level required nested exception priority 00 no interrupt or swilp priorities 0, 1, 2, 3 01 priority 0 priorities 1, 2, 3 10 priority 1 priorities 2, 3 11 priorities 2 or 3 priority 3 f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .
70 56f8356 technical data preliminary 5.4 block diagram figure 5-1 interrupt controller block diagram 5.5 operating modes the itcn module design contains two major modes of operation: ? functional mode the itcn is in this mode by default. ? wait and stop modes during wait and stop modes, the system clocks and the 56800e core are turned off. the itcn will signal a pending irq to the system integration module (sim) to restart the clocks and service the irq. an irq can only wake up the core if the irq is enabled prior to entering the wait or stop mode. also, the irqa and irqb signals automatically become low-level sensitive in these modes even if the control register bits are set to make them falling-edge sensitive. this is because there is no clock available to detect the falling edge. a peripheral which requires a clock to generate interrupts will not be able to generate interrupts during stop mode. the flexcan module can wake the device from stop mode, and a reset will do just that, or irqa and irqb can wake it up. priority level 2 -> 4 decode int1 priority level 2 -> 4 decode int82 level 0 82 -> 7 priority encoder any0 level 3 82 -> 7 priority encoder any3 int vab ipic control 7 7 pic_en iack sr[9:8] f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .

98 56f8356 technical data preliminary 6.3 operating modes since the sim is responsible for distributing clocks and resets across the chip, it must understand the various chip operating modes and take appropriate action. these are: ? reset mode, which has two submodes: por and reset operation the 56800e core and all peripherals are reset. this occurs when the internal por is asserted or the reset pin is asserted. cop reset and software reset operation the 56800e core and all peripherals are reset. the ma bit within the omr is not changed. this allows the software to determine the boot mode (internal or external boot) to be used on the next reset. ? run mode this is the primary mode of operation for this device. in this mode, the 56800e controls chip operation. ? debug mode the 56800e is controlled via jtag/eonce when in debug mode. all peripherals, except the cop and pwms, continue to run. cop is disabled and pwm outputs are optionally switched off to disable any motor from being driven; see the pwm chapter in the 56f8300 peripheral user manual for details. ? wait mode in wait mode, the core clock and memory clocks are disabled. optionally, the cop can be stopped. similarly, it is an option to switch off pwm outputs to disable any motor from being driven. all other peripherals continue to run. ? stop mode when in stop mode, the 56800e core, memory, and most peripheral clocks are shut down. optionally, the cop and can can be stopped. for lowest power consumption in stop mode, the pll can be shut down. this must be done explicitly before entering stop mode, since there is no automatic mechanism for this. the can (along with any non-gated interrupt) is capable of waking the chip up from stop mode, but is not fully functional in stop mode. 6.4 operating mode register figure 6-1 omr see section 4.2 for detailed information on how the operating mode register (omr) ma and mb bits operate in this device. for additional information on the ex bit, see section 4.4 . for all other bits, see the dsp56800e reference manual . note: the omr is not a memory map register; it is directly accessible in code through the acronym omr. bit 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 nl cm xp sd r sa ex 0 mb ma type r/w r/w r/w r/w r/w r/w r/w r/w r/w reset 0000000000000000 f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .

112 56f8356 technical data preliminary 6.6 clock generation overview the sim uses an internal master clock from the occs (clkgen) module to produce the peripheral and system (core and memory) clocks. the maximum master clock frequency is 120mhz. peripheral and system clocks are generated at half the master clock frequency and therefore at a maximum 60mhz. the sim provides power modes (stop, wait) and clock enables (sim_pce register, clk_dis, once_ebl) to control which clocks are in operation. the occs, power modes, and clock enables provide a flexible means to manage power consumption. power utilization can be minimized in several ways. in the occs, crystal oscillator, and pll may be shut down when not in use. when the pll is in use, its prescaler and postscaler can be used to limit pll and master clock frequency. power modes permit system and/or peripheral clocks to be disabled when unused. clock enables provide the means to disable individual clocks. some peripherals provide further controls to disable unused subfunctions. refer to the part 3, on-chip clock synthesis (occs) and the 56f8300 peripheral user manual for further details. 6.7 power-down modes overview the 56f8356 operates in one of three power-down modes, as shown in table 6-3 . all peripherals, except the cop/watchdog timer, run off the ipbus clock frequency, which is the same as the main processor frequency in this architecture. the maximum frequency of operation is sys_clk = 60mhz. table 6-3 clock operation in power-down modes mode core clocks peripheral clocks description run active active device is fully functional wait core and memory clocks disabled active peripherals are active and can product interrupts if they have not been masked off. interrupts will cause the core to come out of its suspended state and resume normal operation. typically used for power-conscious applications. stop system clocks continue to be generated in the sim, but most are gated prior to reaching memory, core and peripherals. the only possible recoveries from stop mode are: 1. can traffic (1st message will be lost) 2. non-clocked interrupts 3. cop reset 4. external reset 5. power-on reset f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .
stop and wait mode disable function 56f8356 technical data 113 preliminary 6.8 stop and wait mode disable function figure 6-16 internal stop disable circuit the 56800e core contains both stop and wait instructions. both put the cpu to sleep. for lowest power consumption in stop mode, the pll can be shut down. this must be done explicitly before entering stop mode, since there is no automatic mechanism for this. when the pll is shut down, the 56800e system clock must be set equal to the prescaler output. some applications require the 56800e stop and wait instructions be disabled. to disable those instructions, write to the sim control register (sim_control), described in section 6.5.1 . this procedure can be on either a permanent or temporary basis. permanently assigned applications last only until their next reset. 6.9 resets the sim supports four sources of reset. the two asynchronous sources are the external reset pin and the power-on reset (por). the two synchronous sources are the software reset, which is generated within the sim itself by writing to the sim_control register and the cop reset. reset begins with the assertion of any of the reset sources. release of reset to various blocks is sequenced to permit proper operation of the device. a por reset is first extended for 2 21 clock cycles to permit stabilization of the clock source, followed by a 32 clock window in which sim clocking is initiated. it is then followed by a 32 clock window in which peripherals are released to implement flash security, and, finally, followed by a 32 clock window in which the core is initialized. after completion of the described reset sequence, application code will begin execution. resets may be asserted asynchronously, but are always released internally on a rising edge of the system clock. d-flop dq c d-flop d q c r 56800e stop_dis permanent disable reprogrammable disable clock select reset note: wait disable circuit is similar f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .
114 56f8356 technical data preliminary part 7 security features the 56f8356 offers security features intended to prevent unauthorized users from reading the contents of the flash memory (fm) array. the 56f8356s flash security consists of several hardware interlocks that block the means by which an unauthorized user could gain access to the flash array. however, part of the security must lie with the users code. an extreme example would be users code that dumps the contents of the internal program, as this code would defeat the purpose of security. at the same time, the user may also wish to put a backdoor in his program. as an example, the user downloads a security key through the sci, allowing access to a programming routine that updates parameters stored in another section of the flash. 7.1 operation with security enabled once the user has programmed the flash with his application code, the 56f8356 can be secured by programming the security bytes located in the fm configuration field, which occupies a portion of the fm array. these non-volatile bytes will keep the part secured through reset and through power-down of the device. only two bytes within this field are used to enable or disable security. refer to the flash memory section in the 56f8300 peripheral user manual for the state of the security bytes and the resulting state of security. when flash security mode is enabled in accordance with the method described in the flash memory module specification, the 56f8356 will disable external p-space accesses restricting code execution to internal memory, disable extboot = 1 mode, and disable the core eonce debug capabilities. normal program execution is otherwise unaffected. 7.2 flash access blocking mechanisms the 56f8356 has several operating functional and test modes. effective flash security must address operating mode selection and anticipate modes in which the on-chip flash can be compromised and read without explicit user permission. methods to block these are outlined in the next subsections. 7.2.1 forced operating mode selection at boot time, the sim determines in which functional modes the 56f8356 will operate. these are: ? internal boot mode ? external boot mode ? secure mode when flash security is enabled as described in the flash memory module specification, the 56f8356 will boot in internal boot mode, disable all access to external p-space, and start executing code from the boot flash at address 0x02_0000. this security affords protection only to applications in which the 56f8356 operates in internal flash security mode. therefore, the security feature cannot be used unless all executing code resides on-chip. when security is enabled, any attempt to override the default internal operating mode by asserting the extboot pin in conjunction with reset will be ignored. f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .
flash access blocking mechanisms 56f8356 technical data 115 preliminary 7.2.2 disabling eonce access on-chip flash can be read by issuing commands across the eonce port, which is the debug interface for the 56800e core. the trst , tclk, tms, tdo, and tdi pins comprise a jtag interface onto which the eonce port functionality is mapped. when the 56f8356 boots, the chip-level jtag tap (test access port) is active and provides the chips boundary scan capability and access to the id register. proper implementation of flash security requires that no access to the eonce port is provided when security is enabled. the 56800e core has an input which disables reading of internal memory via the jtag/eonce. the fm sets this input at reset to a value determined by the contents of the fm security bytes. 7.2.3 flash lockout_recovery if a user inadvertently enables security on the 56f8356, a lockout recovery mechanism is provided which allows the complete erasure of the internal flash contents, including the configuration field, and thus disables security (the protection register is cleared). this does not compromise security, as the entire contents of the users secured code stored in flash are erased before security is disabled on the 56f8356 on the next reset or power-up sequence. to start the lockout recovery sequence, the jtag public instruction (lockout_recovery) must first be shifted into the chip-level tap controllers instruction register. the lockout_recovery instruction will have an associated 7-bit data register (dr) that is used to control the clock divider circuit within the fm module. this divider, fm_clkdiv[6:0], is used to control the period of the clock used for timed events in the fm erase algorithm. this register must be set with appropriate values before the lockout sequence can begin. refer to the jtag section of the 56f8300 peripheral user manual for more details on setting this register value. the value of the jtag fm_clkdiv[6:0] will replace the value of the fm register fmclkd that divides down the system clock for timed events, as illustrated in figure 7-1 . fm_clkdiv[6] will map to the prdiv8 bit, and fm_clkdiv[5:0] will map to the div[5:0] bits. the combination of prdiv8 and div must divide the fm input clock down to a frequency of 150khz-200khz. the writing the fmclkd register section in the flash memory chapter of the 56f8300 peripheral user manual gives specific equations for calculating the correct values. f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .
116 56f8356 technical data preliminary figure 7-1 jtag to fm connection for lockout_recovery two examples of fm_clkdiv calculations follow. example 1: if the system clock is the 8mhz crystal frequency because the pll has not been set up, the input clock will be below 12.8mhz, so prdiv8 = fm_clkdiv[6] = 0. using the following equation yields a div value of 19 for a clock of 200khz, and a div value of 20 for a clock of 190khz. this translates into an fm_clkdiv[6:0] value of $13 or $14, respectively. example 2: in this example, the system clock has been set up with a value of 32mhz, making the fm input clock 16mhz. because that is greater than 12.8mhz, prdiv8 = fm_clkdiv[6] = 1. using the following equation yields a div value of 9 for a clock of 200khz, and a div value of 10 for a clock of 181khz. this translates to an fm_clkdiv[6:0] value of $49 or $4a, respectively. once the lockout_recovery instruction has been shifted into the instruction register, the clock divider value must be shifted into the corresponding 7-bit data register. after the data register has been updated, the user must transition the tap controller into the run-test/idle state for the lockout sequence to commence. the controller must remain in this state until the erase sequence has completed. for details, see the jtag section in the 56f8300 peripheral user manual . note: once the lockout recovery sequence has completed, the user must reset both the jtag tap controller (by asserting trst ) and the 56f8356 (by asserting external chip reset) to return to normal unsecured operation. sys_clk jtag fmclkd divider 7 7 7 2 fm_clkdiv fm_erase flash memory clock input sys_clk (2) ) ( < < (div + 1) 150[khz] 200[khz] sys_clk (2)(8) ) ( < < (div + 1) 150[khz] 200[khz] f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .
flash access blocking mechanisms 56f8356 technical data 117 preliminary 7.2.4 product analysis the recommended method of unsecuring a programmed 56f8356 for product analysis of field failures is via the backdoor key access. the customer would need to supply motorola with the backdoor key and the protocol to access the backdoor routine in the flash. additionally, the keyen bit that allows backdoor key access must be set. an alternative method for performing analysis on a secured hybrid controller would be to mass-erase and reprogram the flash with the original code, but modify the security bytes. to insure that a customer does not inadvertently lock himself out of the 56f8356 during programming, it is recommended that he program the backdoor access key first, his application code second, and the security bytes within the fm configuration field last. f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .

general characteristics 56f8356 technical data 123 preliminary part 10 specifications 10.1 general characteristics the 56f8356 is fabricated in high-density cmos with 5v-tolerant ttl-compatible digital inputs. the term 5v-tolerant refers to the capability of an i/o pin, built on a 3.3v-compatible process technology, to withstand a voltage up to 5.5v without damaging the device. many systems have a mixture of devices designed for 3.3v and 5v power supplies. in such systems, a bus may carry both 3.3v- and 5v-compatible i/o voltage levels (a standard 3.3v i/o is designed to receive a maximum voltage of 3.3v 10% during normal operation without causing damage). this 5v-tolerant capability therefore offers the power savings of 3.3v i/o levels combined with the ability to receive 5v levels without damage. absolute maximum ratings in table 10-1 are stress ratings only, and functional operation at the maximum is not guaranteed. stress beyond these ratings may affect device reliability or cause permanent damage to the device. note: all specifications meet both automotive and industrial requirements unless individual specifications are listed. caution this device contains protective circuitry to guard against damage due to high static voltage or electrical fields. however, normal precautions are advised to avoid application of any voltages higher than maximum-rated voltages to this high-impedance circuit. reliability of operation is enhanced if unused inputs are tied to an appropriate voltage level. f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .

equivalent circuit for adc inputs 56f8356 technical data 147 preliminary significantly reduced (by as much as 28%) the collective variation (spread) of the absolute error of the population. it also significantly reduced (by as much as 80%) the mean (average) of the absolute error and thereby brought it significantly closer to the ideal value of zero. although not guaranteed, it is believed that calibration will produce results similar to those shown above for any population of parts including those which represent processing and temperature extremes. 10.17 equivalent circuit for adc inputs figure 10-23 illustrates the adc input circuit during sample and hold. s1 and s2 are always open/closed at the same time that s3 is closed/open. when s1/s2 are closed & s3 is open, one input of the sample and hold circuit moves to v refh - v refh / 2, while the other charges to the analog input voltage. when the switches are flipped, the charge on c1 and c2 are averaged via s3, with the result that a single-ended analog input is switched to a differential voltage centered about v refh - v refh / 2. the switches switch on every cycle of the adc clock (open one-half adc clock, closed one-half adc clock). note that there are additional capacitances associated with the analog input pad, routing, etc., but these do not filter into the s/h output voltage, as s1 provides isolation during the charge-sharing phase. one aspect of this circuit is that there is an on-going input current, which is a function of the analog input voltage, v ref and the adc clock frequency. 1. parasitic capacitance due to package, pin-to-pin and pin-to-package base coupling; 1.8pf 2. parasitic capacitance due to the chip bond pad, esd protection devices and signal routing; 2.04pf 3. equivalent resistance for the esd isolation resistor and the channel select mux; 500 ohms 4. sampling capacitor at the sample and hold circuit. capacitor c1 is normally disconnected from the input and is only connected to it at sampling time; 1pf figure 10-23 equivalent circuit for a/d loading 10.18 power consumption this section provides additional detail which can be used to optimize power consumption for a given application. power consumption is given by the following equation: total power = a: internal [static component] + b: internal [state-dependent component] + c: internal [dynamic component] + d: external [dynamic component] + e: external [static] 1 2 3 analog input 4 s1 s2 s3 c1 c2 s/h c1 = c2 = 1pf (v refh - v reflo ) / 2 f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .
148 56f8356 technical data preliminary a, the internal [static component], is comprised of the dc bias currents for the oscillator, pll, leakage current, and voltage references. these sources operate independently of processor state or operating frequency. b, the internal [state-dependent component], reflects the supply current required by certain on-chip resources only when those resources are in use. these include ram, flash memory and the adcs. c, the internal [dynamic component], is classic c*v 2 *f cmos power dissipation corresponding to the 56800e core and standard cell logic. d, the external [dynamic component], reflects power dissipated on-chip as a result of capacitive loading on the external pins of the chip. this is also commonly described as c*v 2 *f, although simulations on two of the io cell types used on the 56f8356 reveal that the power-versus-load curve does have a non-zero y-intercept. power due to capacitive loading on output pins is (first order) a function of the capacitive load and frequency at which the outputs change. table 10-25 provides coefficients for calculating power dissipated in the io cells as a function of capacitive load. in these cases: totalpower = ((intercept +slope*cload)*frequency/10mhz) where: ? summation is performed over all output pins with capacitive loads ? totalpower is expressed in mw ? cload is expressed in pf because of the low duty cycle on most device pins, power dissipation due to capacitive loads was found to be fairly low when averaged over a period of time. the one possible exception to this is if the chip is using the external address and data buses at a rate approaching the maximum system rate. in this case, power from these buses can be significant. e, the external [static component], reflects the effects of placing resistive loads on the outputs of the device. sum the total of all v 2 /r or iv to arrive at the resistive load contribution to power. assume v = 0.5 for the purposes of these rough calculations. for instance, if there is a total of 8 pwm outputs driving 10ma into leds, then p = 8*.5*.01 = 40mw. in previous discussions, power consumption due to parasitics associated with pure input pins is ignored, as it is assumed to be negligible. table 10-25 io loading coefficients at 10mhz intercept slope pdu08dgz_me 1.3 0.11mw / pf pdu04dgz_me 1.15mw 0.11mw / pf f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .

thermal design considerations 56f8356 technical data 153 preliminary part 12 design considerations 12.1 thermal design considerations an estimation of the chip junction temperature, t j , can be obtained from the equation: t j = t a + (r j x p d ) where: the junction-to-ambient thermal resistance is an industry-standard value that provides a quick and easy estimation of thermal performance. unfortunately, there are two values in common usage: the value determined on a single-layer board and the value obtained on a board with two planes. for packages such as the pbga, these values can be different by a factor of two. which value is closer to the application depends on the power dissipated by other components on the board. the value obtained on a single-layer board is appropriate for the tightly packed printed circuit board. the value obtained on the board with the internal planes is usually appropriate if the board has low-power dissipation and the components are well separated. when a heat sink is used, the thermal resistance is expressed as the sum of a junction-to-case thermal resistance and a case-to-ambient thermal resistance: r j = r j + r c where: r jc is device-related and cannot be influenced by the user. the user controls the thermal environment to change the case-to-ambient thermal resistance, r ca . for instance, the user can change the size of the heat sink, the air flow around the device, the interface material, the mounting arrangement on printed circuit board, or change the thermal dissipation on the printed circuit board surrounding the device. to determine the junction temperature of the device in the application when heat sinks are not used, the thermal characterization parameter ( jt ) can be used to determine the junction temperature with a measurement of the temperature at the top center of the package case using the following equation: t j = t t + ( jt x p d ) where: t a = ambient temperature for the package ( o c) r j = junction-to-ambient thermal resistance ( o c/w) p d = power dissipation in the package (w) r ja = package junction-to-ambient thermal resistance c/w r jc = package junction-to-case thermal resistance c/w r ca = package case-to-ambient thermal resistance c/w t t = thermocouple temperature on top of package ( o c) jt = thermal characterization parameter ( o c)/w p d = power dissipation in package (w) f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .
154 56f8356 technical data preliminary the thermal characterization parameter is measured per jesd51-2 specification using a 40-gauge type t thermocouple epoxied to the top center of the package case. the thermocouple should be positioned so that the thermocouple junction rests on the package. a small amount of epoxy is placed over the thermocouple junction and over about 1mm of wire extending from the junction. the thermocouple wire is placed flat against the package case to avoid measurement errors caused by cooling effects of the thermocouple wire. when heat sink is used, the junction temperature is determined from a thermocouple inserted at the interface between the case of the package and the interface material. a clearance slot or hole is normally required in the heat sink. minimizing the size of the clearance is important to minimize the change in thermal performance caused by removing part of the thermal interface to the heat sink. because of the experimental difficulties with this technique, many engineers measure the heat sink temperature and then back-calculate the case temperature using a separate measurement of the thermal resistance of the interface. from this case temperature, the junction temperature is determined from the junction-to-case thermal resistance. 12.2 electrical design considerations use the following list of considerations to assure correct device operation: ? provide a low-impedance path from the board power supply to each v dd pin on the device, and from the board ground to each v ss (gnd) pin ? the minimum bypass requirement is to place six 0.01C0.1 f capacitors positioned as close as possible to the package supply pins. the recommended bypass configuration is to place one bypass capacitor on each of the v dd /v ss pairs, including v dda /v ssa. ceramic and tantalum capacitors tend to provide better performance tolerances. ? ensure that capacitor leads and associated printed circuit traces that connect to the chip v dd and v ss (gnd) pins are less than 0.5 inch per capacitor lead ? use at least a four-layer printed circuit board (pcb) with two inner layers for v dd and v ss ? bypass the v dd and v ss layers of the pcb with approximately 100 f, preferably with a high-grade capacitor such as a tantalum capacitor ? because the 56f8356s output signals have fast rise and fall times, pcb trace lengths should be minimal caution this device contains protective circuitry to guard against damage due to high static voltage or electrical fields. however, normal precautions are advised to avoid application of any voltages higher than maximum-rated voltages to this high-impedance circuit. reliability of operation is enhanced if unused inputs are tied to an appropriate voltage level. f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .
power distribution and i/o ring implementation 56f8356 technical data 155 preliminary ? consider all device loads as well as parasitic capacitance due to pcb traces when calculating capacitance. this is especially critical in systems with higher capacitive loads that could create higher transient currents in the v dd and v ss circuits. ? take special care to minimize noise levels on the v ref , v dda and v ssa pins ? designs that utilize the trst pin for jtag port or eonce module functionality (such as development or debugging systems) should allow a means to assert trst whenever reset is asserted, as well as a means to assert trst independently of reset . designs that do not require debugging functionality, such as consumer products, should tie these pins together. ? because the flash memory is programmed through the jtag/eonce port, the designer should provide an interface to this port to allow in-circuit flash programming 12.3 power distribution and i/o ring implementation figure 12-1 illustrates the general power control incorporated in the 56f8356. this chip contains an internal regulator which cannot be disabled. the regulator takes regulated 3.3v power from the v dd_io pins and provides 2.5v to the internal logic of the chip. this means the entire part is powered from the 3.3v supply. notes: ? flash, ram and internal logic are powered from the core regulator output ?v pp 1 and v pp 2 are not connected in the customer system ? all circuitry, analog and digital, shared a common v ss bus figure 12-1 56f8356 power management reg core v cap i/o adc v dd v ss ocs reg v dda_osc_pll rosc v ssa_adc v dda_adc v refh v refp v refmid v refn v reflo f r e e s c a l e s e m i c o n d u c t o r , i freescale semiconductor, inc. f o r m o r e i n f o r m a t i o n o n t h i s p r o d u c t , g o t o : w w w . f r e e s c a l e . c o m n c . . .
