(where x = 1...6). each voltage monitor can be divided into two sections: analog input, and filtering. the voltage input is monitored by a programmable trip-point comparator. table 1 and table 2 show all trip points and ranges to which any comparators threshold can be set. tms tck state vih vil vih vil update-ir run-test/idle (program) select-dr scan clock to shift-ir state and shift in the next instruction update-ir t h t h t h t h t h t ckh t ckh t ckh t ckl t pwv t ckh t ckl t su1 t su1 t su1 t su1 t su1 tms tck state vih vil vih vil update-ir run-test/idle (erase or program) select-dr scan clock to shift-ir state and shift in the verify instruction, then clock to the run-test/idle state run-test/idle (verify) specified by the data sheet actual t h t h t h t h t h t h t su1 t ckh t hvdis (actual) t ckh t ckh t ckh t ckl t pwp t pwv t ckh t ckl t pwv t su1 t su1 t su1 t su1 t su1 logic signal analog input vmonx trip point glitch filter pld array processorpm-powr605
lattice semiconductor processorpm-powr605 data sheet 11 each comparator outputs a high signal to the pld array if the voltage at its positive terminal (vmonx pin) is greater than its programmed trip point setting, otherwise it outputs a low signal. a hysteresis of approximately 1% of the setpoint is provided by the comparators to reduce false triggering as a result of input noise. the hysteresis provided by the voltage monitor is a function of the input divider setting. table 3 lists the typical hysteresis versus voltage monitor trip-point. programmable over-voltage and under-voltage thresholds figure 10 (a) shows the power supply ramp-up and ramp-down voltage waveforms. because of hysteresis, the comparator outputs change state at different thresholds depending on the direction of excursion of the monitored power supply. figure 10.

lattice semiconductor processorpm-powr605 data sheet 14 figure 11. processorpm-powr605 pld architecture macrocell architecture the macrocell shown in figure 12 is the heart of the pld. the basic macrocell has ?e product terms that feed the or gate and the ?p-?p. the ?p-?p in each macrocell is independently con?ured. it can be programmed to function as a d-type or t-type ?p-?p. combinatorial functions are realized by bypassing the ?p-?p. the polarity control and xor gates provide additional ?xibility for logic synthesis. the ?p-?ps clock is driven from the com- mon pld clock that is generated by dividing the 8 mhz master clock (mclk) by 32. the macrocell also supports asynchronous reset and preset functions, derived from either product terms or the power-on reset signal. the resources within the macrocells share routing and contain a product term allocation array. the product term alloca- tion array greatly expands the plds ability to implement complex logical functions by allowing logic to be shared between adjacent blocks and distributing the product terms to allow for wider decode functions. all the digital inputs are registered by mclk and all vmon comparator outputs are registered using the pld clock to synchronize them to the pld logic as shown in figure 11. reset output feedback 16 vmon[1:6] 6 timer1 timer0 timer2 timer3 i r p timer clock 16 pld clock mclk 4 16 in2 and array 28 inputs input register input register 81 p-terms sleep/ wake logic in1_pwrdn vcc glb generic logic block 16 macrocell 81 p-terms 81 pld_pwrdn in_out[1:5]

lattice semiconductor processorpm-powr605 data sheet 16 digital inputs and optional device power down the processorpm-powr605 has two dedicated digital input pins which are registered by mclk as shown in figure 11, then connected to to the input and array of the pld (in[1:2]). the pins are standard cmos inputs and are referenced to vcc. the optional power-down mode is a programmable feature controlled via the in1_pwrdn pin. it is used to power- down the processorpm-powr605 and power it up again as desired. when in power-down mode, the proces- sorpm-powr605 draws a minimal amount of supply current (less than 10? max). the device is brought out of power-down mode by applying a logic high signal on the level sensitive in1_pwrdn pin. when it exits power-down mode, the processorpm-powr605 is internally reset to its initial power-on state before resuming normal operation. the logic and limited memory needed to ?akeup on cue are all that remain on during power-down mode. other functions and capabilities such as voltage monitoring and pld logic states are all lost when the processorpm-powr605 is in power-down mode. open drain outputs go into hi-z mode and all digital inputs, except in1_pwrdn , stop responding to logic input signals. there are two e 2 cmos bits associated with the processorpm-powr605 power-down function. con?uring these bits for speci? power-down functionality is achieved using pac-designer, a software design tool for lattice pro- grammable mixed signal devices. table 4 is a truth table detailing the operation of the processorpm-powr605 power-down logical control function. table 4. pwrdn truth table to use the processorpm-powr605's power-down function, the e 2 cmos pwrdn enable bit must be set during initial device design con?uration. power-down is disabled otherwise (the initial default). when power is ?st applied to processorpm-powr605, the device checks to see if a power-down condition exists, and then if it is already present will proceed immediately to the power-down state. during the brief period that the device is on, it will consume full power but it will proceed directly to power-down mode without executing any state machine instructions, etc. this time to initially detect the power-down command and then shut down is given in the power-down speci?ations section of the datasheet. in addition to the in1_pwrdn pin, table 4 shows how an alternate signal from the pld called pld_pwrdn can be used to initiate power-down (not the default). this can be useful when power-down is the last step in a series of processorpm-powr605 pld controlled states, such as turning off supplies in sequence or acknowledging pro- cessor signals, etc. note : the only way to exit power-down mode, regardless of how it's initiated, is with the in1_pwrdn pin. applying a logic high to in1_pwrdn will always return the processorpm-powr605 to normal operation. finally, whenever the processorpm-powr605 is in power-down mode, vccj is internally pulled to gnd to turn off the jtag i/o pins. it is important, therefore, that the vccj pin be open when power-down mode is initiated. if connected to a power supply during power-down mode, vccj will draw approximately 2.2ma. dual purpose digital i/o pins the processorpm-powr605 provides ?e possible digital outputs, in_out[1:5]. any number of these pins can be con?ured to act as open drain outputs, providing a high degree of ?xibility when interfacing to logic signals, in1_ p p p p w w w w r r r r d d d d n n n n input pin pld_pwrdn internal signal pwrdn enable bit pwrdn source bit power mode x x clear x normal 1 x set x normal 0 x set in1_ pwrdn pin power-down 0 0 set internal signal pld_pwrdn power-down note: when in power-down mode, the processorpm-powr605 will not respond to logic inputs (except to the in1_ pwrdn pin) and all outputs will be high impedance.

lattice semiconductor processorpm-powr605 data sheet 18 figure 15. pac-designer processorpm-powr605 design entry screen in-system programming the processorpm-powr605 is an in-system programmable device. this is accomplished by integrating all e 2 con- ?uration memory on-chip. programming is performed through a 4-wire, ieee 1149.1 compliant serial jtag inter- face at normal logic levels. once a device is programmed, all con?uration information is stored on-chip, in non- volatile e 2 cmos memory cells. the speci?s of the ieee 1149.1 serial interface and all processorpm-powr605 instructions are described in the jtag interface section of this data sheet. user electronic signature a user electronic signature (ues) feature is included in the e 2 cmos memory of the processorpm-powr605. this consists of 32 bits that can be con?ured by the user to store unique data such as id codes, revision numbers or inventory control data. the speci?s of this feature are discussed in the ieee 1149.1 serial interface section of this data sheet. electronic security an electronic security ?use (esf) bit is provided in every processorpm-powr605 device to prevent unauthorized readout of the e 2 cmos con?uration bit patterns. once programmed, this cell prevents further access to the func- tional user bits in the device. this cell can only be erased by reprogramming the device, so the original con?ura- tion cannot be examined once programmed. usage of this feature is optional. the speci?s of this feature are discussed in the ieee 1149.1 serial interface section of this data sheet. production programming support once a ?al con?uration is determined, an ascii format jedec ?e can be created using the pac-designer soft- ware. devices can then be ordered through the usual supply channels with the users speci? con?uration already preloaded into the devices. by virtue of its standard interface, compatibility is maintained with existing production programming equipment, giving customers a wide degree of freedom and ?xibility in production planning.
lattice semiconductor processorpm-powr605 data sheet 19 initial factory con?uration processorpm devices are factory precon?ured to integrate a programmable 6-supply reset generator (con?ured through pin strapping) and a programmable watchdog timer (con?ured through pin strapping). see figure 17. programmable reset generator the integrated reset generator activates (active low) the reset_cpu signal (figure 2) when any of the six supplies are less than their fault level. when all supplies are stable and the pulse stretch function is enabled the reset_cpu signal will be deactivated after 200 ms. manual_reset input when the manual_reset input is pulled low, the reset_cpu gets activated immediately. when the reset input is released, the reset output also gets released. the manual reset input is debounced with a 50 ms timer. voltage threshold setting: vmon1 to vmon3 thresholds are set to 3.3v - 5%, 2.5v - 5% and 1.8v - 5% respectively vmon4 to vmon6 thresholds are set at 0.669v. these vmon inputs can be used to monitor supply rails from 0.669v to 24v or higher using external resistor-based potential dividers. the resistor values are calculated using the formula shown in figure 16. when monitoring fewer than six supplies, all unused vmon inputs should be connected to 3.3v rail. figure 16. setting fault threshold using external resistors for vmon4, vmon5 and vmon6 programmable reset pulse stretching some reset generator functions require that the reset pulse be held active for an extended period of time after the supplies are stabilized. one can introduce a 200 ms pulse stretch by connecting the stretch_200ms pin to 3.3v. if the stretch_200ms pin is grounded the reset pulse stretch function will be disabled. programmable watchdog timer watchdog timers are used to monitor system software health. the processor generates a watchdog trigger (wdt_trig) signal periodically to trigger the watchdog timer. if the processor fails to trigger within the stipulated duration, the watchdog timer generates a watchdog timer interrupt for the processor. the interval between succes- sive watchdog triggers depends on the application. in this design, the watchdog timer duration can be programmed by using two pins, wdt_sel0 and wdt_sel1. refer to figure 17. r1 = r2 * ( ( v rail * (1-f/100)) vt -1 ) v rail ? monitored supply rail voltage f ? supply fault tolerance level in % vt ? vmon threshold setting = 0.669v note: this equation assumes that r2 3k ohm vt - internal threshold 0.669v vmon4..6 r1 r2 v rail processorpm adjx

lattice semiconductor processorpm-powr605 data sheet 22 figure 19. tap states when the correct logic sequence is applied to the tms and tck inputs, the tap will exit the test-logic-reset state and move to the desired state. the next state after test-logic-reset is run-test/idle. until a data or instruction shift is performed, no action will occur in run-test/idle (steady state = idle). after run-test/idle, either a data or instruc- tion shift is performed. the states of the data and instruction register blocks are identical to each other differing only in their entry points. when either block is entered, the ?st action is a capture operation. for the data regis- ters, the capture-dr state is very simple: it captures (parallel loads) data onto the selected serial data path (previ- ously chosen with the appropriate instruction). for the instruction register, the capture-ir state will always load the idcode instruction. it will always enable the id register for readout if no other instruction is loaded prior to a shift-dr operation. this, in conjunction with mandated bit codes, allows a ?lind interrogation of any device in a compliant ieee 1149.1 serial chain. from the capture state, the tap transitions to either the shift or exit1 state. normally the shift state follows the capture state so that test data or status information can be shifted out or new data shifted in. following the shift state, the tap either returns to the run-test/idle state via the exit1 and update states or enters the pause state via exit1. the pause state is used to temporarily suspend the shifting of data through either the data or instruction register while an external operation is performed. from the pause state, shifting can resume by reentering the shift state via the exit2 state or be terminated by entering the run-test/idle state via the exit2 and update states. if the proper instruction is shifted in during a shift-ir operation, the next entry into run-test/idle initiates the test mode (steady state = test). this is when the device is actually programmed, erased or veri?d. all other instructions are executed in the update state. test instructions like data registers, the ieee 1149.1 standard also mandates the inclusion of certain instructions. it outlines the function of three required and six optional instructions. any additional instructions are left exclusively for the manu- facturer to determine. the instruction word length is not mandated other than to be a minimum of two bits, with only the bypass and extest instruction code patterns being speci?ally called out (all ones and all zeroes respec- tively). the processorpm-powr605 contains the required minimum instruction set as well as one from the optional instruction set. in addition, there are several proprietary instructions that allow the device to be con?ured test-logic-rst run-test/idle select-dr-scan select-ir-scan capture-dr capture-ir shift-dr shift-ir exit1-dr exit1-ir pause-dr pause-ir exit2-dr exit2-ir update-dr update-ir 1 0 00 00 00 11 00 00 11 11 00 11 00 11 11 11 1 0 note: the value shown adjacent to each state transition in this figure represents the signal present at tms at the time of a rising edge at tck.
