preliminary information 1-6 dsp56011 technical data sheet, rev. 1 motorola signal/connection descriptions interrupt and mode control preliminary interrupt and mode control table 1-5 interrupt and mode control signal name type state during reset signal description moda irqa input input input (moda) mode select a ?his input signal has three functions: to work with the modb and modc signals to select the dsp? initial operating mode, to allow an external device to request a dsp interrupt after internal synchronization, and to turn on the internal clock generator when the dsp is in the stop processing state, causing the dsp to resume processing. moda is read and internally latched in the dsp when the processor exits the reset state. the logic state present on the moda, modb, and modc pins selects the initial dsp operating mode. several clock cycles after leaving the reset state, the moda signal changes to the external interrupt request irqa . the dsp operating mode can be changed by software after reset. external interrupt request a (irqa ) ?he irqa input is a synchronized external interrupt request. it may be programmed to be level-sensitive or negative-edge triggered. when the signal is edge-triggered, triggering occurs at a voltage level and is not directly related to the fall time of the interrupt signal. however, as the fall time of the interrupt signal increases, the probability that noise on irqa will generate multiple interrupts also increases. while the dsp is in the stop mode, asserting irqa gates on the oscillator and, after a clock stabilization delay, enables clocks to the processor and peripherals. hardware reset causes this input to function as moda.
preliminary information motorola dsp56011 technical data sheet, rev. 1 1-7 signal/connection descriptions interrupt and mode control preliminary modb irqb input input input (modb) mode select b ?his input signal has two functions: to work with the moda and modc signals to select the dsp? initial operating mode, and to allow an external device to request a dsp interrupt after internal synchronization. modb is read and internally latched in the dsp when the processor exits the reset state. the logic state present on the moda, modb, and modc pins selects the initial dsp operating mode. several clock cycles after leaving the reset state, the modb signal changes to the external interrupt request irqb . the dsp operating mode can be changed by software after reset. external interrupt request b (irqb )?he irqb input is a synchronized external interrupt request. it may be programmed to be level-sensitive or negative-edge triggered. when the signal is edge-triggered, triggering occurs at a voltage level and is not directly related to the fall time of the interrupt signal. however, as the fall time of the interrupt signal increases, the probability that noise on irqb will generate multiple interrupts also increases. hardware reset causes this input to function as modb. table 1-5 interrupt and mode control (continued) signal name type state during reset signal description
preliminary information 1-8 dsp56011 technical data sheet, rev. 1 motorola signal/connection descriptions interrupt and mode control preliminary modc nmi input, edge- triggered input, edge- triggered input (modc) mode select c ?his input signal has two functions: to work with the moda and modb signals to select the dsp? initial operating mode, and to allow an external device to request a dsp interrupt after internal synchronization. modc is read and internally latched in the dsp when the processor exits the reset state. the logic state present on the moda, modb, and modc pins selects the initial dsp operating mode. several clock cycles after leaving the reset state, the modc signal changes to the non-maskable interrupt request, nmi . the dsp operating mode can be changed by software after reset. non-maskable interrupt request ?he nmi input is a negative-edge triggered external interrupt request. this is a level 3 interrupt that can not be masked out. triggering occurs at a voltage level and is not directly related to the fall time of the interrupt signal. however, as the fall time of the interrupt signal increases, the probability that noise on nmi will generate multiple interrupts also increases. hardware reset causes this input to function as modc. reset input active reset this input causes a direct hardware reset of the processor. when reset is asserted, the dsp is initialized and placed in the reset state. a schmitt-trigger input is used for noise immunity. when the reset signal is deasserted, the initial dsp operating mode is latched from the moda, modb, and modc signals. the dsp also samples the pinit signal and writes its status into the pen bit of the pll control register. when the dsp comes out of the reset state, deassertion occurs at a voltage level and is not directly related to the rise time of the reset signal. however, the probability that noise on reset will generate multiple resets increases with increasing rise time of the reset signal. for proper hardware reset to occur, the clock must be active, since a number of clock ticks are required for proper propagation of the hardware reset state. table 1-5 interrupt and mode control (continued) signal name type state during reset signal description

(data is clocked into the once port on the falling edge and is clocked out of the once serial port on the rising edge.) the debug serial clock frequency must be no greater than 1 / 8 of the processor clock frequency. when switching from input to output, the signal is tri-stated. chip status 1 ?hen the chip is not in debug mode, this signal is an output that works with the os0 signal to provide information about the chip status. note: if the once interface is in use, an external pull-down resistor should be attached to this pin. if the once interface is not in use, the resistor is not required.

preliminary information motorola dsp56011 technical data sheet, rev. 1 2-1 preliminary section 2 specifications introduction the dsp56011 is fabricated in high density cmos with transistor-transistor logic (ttl) compatible inputs and outputs. the dsp56011 specifications are preliminary and are from design simulations, and may not be fully tested or guaranteed at this early stage of the product life cycle. for design convenience, timings for 81 mhz and 95 mhz operation are included. finalized specifications will be published after full characterization and device qualifications are complete. maximum ratings note: in the calculation of timing requirements, adding a maximum value of one specification to a minimum value of another specification does not yield a reasonable sum. a maximum specification is calculated using a worst case variation of process parameter values in one direction. the minimum specification is calculated using the worst case for the same parameters in the opposite direction. therefore, a ?aximum?value for a specification will never occur in the same device that has a ?inimum?value for another specification; adding a maximum to a minimum represents a condition that can never exist. caution this device contains circuitry protecting against damage due to high static voltage or electrical fields; however, normal precautions should be taken to avoid exceeding maximum voltage ratings. reliability is enhanced if unused inputs are tied to an appropriate logic voltage level (e.g., either gnd or v cc ).

(this is typical for ceramic capacitors.) for capacitor values greater than 2 nf, asserting reset according to this timing requirement will ensure proper processor initialization for capacitors with a delta c/c less than 0.01%. (this is typical for teflon, polystyrene, and polypropylene capacitors.) however, capacitors with values greater than 2 nf with a delta c/c greater than 0.01% may require longer reset assertion to ensure proper initialization. 2. when using fast interrupts and irqa and irqb are defined as level-sensitive, timing 22 applies to prevent multiple interrupt service. to avoid these timing restrictions, negative-edge-triggered configuration is recommended when using fast interrupts. long interrupts are recommended when using level-sensitive configuration. figure 2-2 reset timing table 2-7 reset, stop, mode select, and interrupt timing (continued) no. characteristics all frequencies unit min max reset 10 v ihr aa0251

preliminary information motorola dsp56011 technical data sheet, rev. 1 2-25 specifications serial host interface (shi) i2c protocol timing preliminary programming the serial clock the programmed serial clock cycle, t i 2 ccp , is specified by the value of the hdm5 hdm0 and hrs bits of the hckr (shi clock control register). the expression for t i 2 ccp is: t i 2 ccp = [t c 2 (hdm[5:0] + 1) (7 (1 ?hrs) + 1)] where hrs is the prescaler rate select bit. when hrs is cleared, the fixed divide- by-eight prescaler is operational. when hrs is set, the prescaler is bypassed. mdm5?dm0 are the divider modulus select bits. a divide ratio from 1 to 64 (hdm5?dm0 = 0 to $3f) may be selected. in i 2 c mode, you may select a value for the programmed serial clock cycle from: 6 t c (if hdm[5:0] = $02 and hrs = 1) to 1024 t c (if hdm[5:0] = $3f and hrs = 0) the dsp56011 provides an improved i 2 c bus protocol. in addition to supporting the 100 khz i 2 c bus protocol, the shi in i 2 c mode supports data transfers at up to 1000 khz. the actual maximum frequency is limited by the bus capacitances (c l ),the pull- up resistors (r p ), (which affect the rise and fall time of sda and scl, see table 2-12 on page 2-26), and by the input filters.
preliminary information 2-26 dsp56011 technical data sheet, rev. 1 motorola specifications serial host interface (shi) i2c protocol timing preliminary considerations for programming the shi clock control register (hckr)?lock divide ratio the master must generate a bus free time greater than t172 slave when operating with a dsp56011 shi i 2 c slave. table 2-12 describes a few examples. example: for c l = 50 pf, r p = 2 k w , f = 81 mhz, bypassed filter mode: the master, when operating with a dsp56011 shi i 2 c slave with an 81 mhz operating frequency, must generate a bus free time greater than 36 ns (t172 slave). thus, the minimum permissible t i 2 ccp is 52 t c , which gives a bus free time of at least 41 ns (t172 master). this implies a maximum i 2 c serial frequency of 1010 khz. in general, bus performance may be calculated from the c l and r p of the bus, the input filter modes and operating frequencies of the master and the slave. table 2-13 on page 2-27 contains the expressions required to calculate all relevant performance timing for a given c l and r p . note: t177 (t r ) is computed using the values of c l and r p and t178 (t f ) is computed using the value of c l . the two values are used in computing many of the other timing values in table 2-13 on page 2-27. table 2-12 considerations for programming the shi clock control register (hckr) conditions to be considered resulting limitations bus load master oper- ating freq. slave oper- ating freq. master filter mode slave filter mode t172 slave min. perm- issible t i 2 ccp t172 master maximum i 2 c serial frequency c l = 50 pf, r p = 2 k w 81 mhz 81 mhz bypassed narrow wide bypassed narrow wide 36 ns 60 ns 95 ns 52 t c 56 t c 62 t c 41 ns 66 ns 103 ns 1010 khz 825 khz 634 khz c l = 50 pf, r p = 2 k w 95 mhz 95 mhz bypassed narrow wide bypassed narrow wide 32 ns 56 ns 91 ns 60 t c 64 t c 71 t c 35 ns 56 ns 92.8 ns 1030 khz 843 khz 645 khz

preliminary information motorola dsp56011 technical data sheet, rev. 1 4-1 preliminary section 4 design considerations thermal design considerations an estimation of the chip junction temperature, t j , in c can be obtained from the equation: equation 1: where: t a = ambient temperature ?c r q ja = package junction-to-ambient thermal resistance ?c/w p d = power dissipation in package historically, thermal resistance has been expressed as the sum of a junction-to-case thermal resistance and a case-to-ambient thermal resistance: equation 2: where: r q ja = package junction-to-ambient thermal resistance ?c/w r q jc = package junction-to-case thermal resistance ?c/w r q ca = package case-to-ambient thermal resistance ?c/w r q 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 q ca . for example, the user can change the air flow around the device, add a heat sink, change the mounting arrangement on the printed circuit board, or otherwise change the thermal dissipation capability of the area surrounding the device on a printed circuit board. this model is most useful for ceramic packages with heat sinks; some 90% of the heat flow is dissipated through the case to the heat sink and out to the ambient environment. for ceramic packages, in situations where the heat flow is split between a path to the case and an alternate path through the printed circuit board, analysis of the device thermal performance may need the additional modeling capability of a system level thermal simulation tool. t j t a p d r q ja () + = r q ja r q jc r q ca + =
preliminary information 4-2 dsp56011 technical data sheet, rev. 1 motorola design considerations thermal design considerations preliminary the thermal performance of plastic packages is more dependent on the temperature of the printed circuit board to which the package is mounted. again, if the estimations obtained from r q ja do not satisfactorily answer whether the thermal performance is adequate, a system level model may be appropriate. a complicating factor is the existence of three common ways for determining the junction-to-case thermal resistance in plastic packages: to minimize temperature variation across the surface, the thermal resistance is measured from the junction to the outside surface of the package (case) closest to the chip mounting area when that surface has a proper heat sink. to define a value approximately equal to a junction-to-board thermal resistance, the thermal resistance is measured from the junction to where the leads are attached to the case. if the temperature of the package case (t t ) is determined by a thermocouple, the thermal resistance is computed using the value obtained by the equation (t j ?t t )/p d . as noted above, the junction-to-case thermal resistances quoted in this data sheet are determined using the first definition. from a practical standpoint, that value is also suitable for determining the junction temperature from a case thermocouple reading in forced convection environments. in natural convection, using the junction-to-case thermal resistance to estimate junction temperature from a thermocouple reading on the case of the package will estimate a junction temperature slightly hotter than actual temperature. hence, the new thermal metric, thermal characterization parameter or y jt , has been defined to be (t j ?t t )/p d . this value gives a better estimate of the junction temperature in natural convection when using the surface temperature of the package. remember that surface temperature readings of packages are subject to significant errors caused by inadequate attachment of the sensor to the surface and to errors caused by heat loss to the sensor. the recommended technique is to attach a 40-gauge thermocouple wire and bead to the top center of the package with thermally conductive epoxy.
preliminary information motorola dsp56011 technical data sheet, rev. 1 4-3 design considerations electrical design considerations preliminary electrical design considerations use the following list of recommendations to assure correct dsp operation: provide a low-impedance path from the board power supply to each v cc pin on the dsp, and from the board ground to each gnd pin. use at least four 0.01?.1 m f bypass capacitors positioned as close as possible to the four sides of the package to connect the v cc power source to gnd. ensure that capacitor leads and associated printed circuit traces that connect to the chip v cc and gnd pins are less than 0.5 in per capacitor lead. use at least a four-layer printed circuit board (pcb) with two inner layers for v cc and gnd. because the dsp output signals have fast rise and fall times, pcb trace lengths should be minimal. this recommendation particularly applies to the address and data buses as well as the irqa , irqb , and nmi pins. maximum printed circuit board (pcb) trace lengths on the order of 6 inches are recommended. 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 cc and gnd circuits. all inputs must be terminated (i.e., not allowed to float) using cmos levels, except as noted in section 1 . take special care to minimize noise levels on the v ccp and gnd p pins. if multiple dsp56011 devices are on the same board, check for cross-talk or excessive spikes on the supplies due to synchronous operation of the devices. 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 logic voltage level (e.g., either gnd or v cc ).
preliminary information 4-4 dsp56011 technical data sheet, rev. 1 motorola design considerations power consumption considerations preliminary power consumption considerations power dissipation is a key issue in portable dsp applications. some of the factors which affect current consumption are described in this section. most of the current consumed by cmos devices is alternating current (ac), which is charging and discharging the capacitances of the pins and internal nodes. current consumption is described by the formula: equation 3: where: c = node/pin capacitance v = voltage swing f = frequency of node/pin toggle the maximum internal current (i cci max) value reflects the typical possible switching of the internal buses on best-case operation conditions, which is not necessarily a real application case. the typical internal current (i ccityp ) value reflects the average switching of the internal buses on typical operating conditions. for applications that require very low current consumption: minimize the number of pins that are switching. minimize the capacitive load on the pins. connect the unused inputs to pull-up or pull-down resistors. disable unused peripherals. disable unused pin activity. example 4-1 current consumption for an i/o pin loaded with 50 pf capacitance, operating at 5.5 v, and with a 81 mhz clock, toggling at its maximum possible rate (20 mhz), the current consumption is: equation 4: i cvf = i5010 12 5.5 20 10 6 5.5ma ==

preliminary information 4-6 dsp56011 technical data sheet, rev. 1 motorola design considerations power-up considerations preliminary power-up considerations to power-up the device properly, ensure that the following conditions are met: stable power is applied to the device according to the specifications in table 2-3 (dc electrical characteristics). the external clock oscillator is active and stable. reset is asserted according to the specifications in table 2-7 (reset, stop, mode select, and interrupt timing). the following input pins are driven to valid voltage levels: dr , pinit, moda, modb, and modc. care should be taken to ensure that the maximum ratings for all input voltages obey the restrictions on table 2-1 (maximum ratings), at all phases of the power-up procedure. this may be achieved by powering the external clock, hardware reset, and mode selection circuits from the same power supply that is connected to the power supply pins of the chip. at the beginning of the hardware reset procedure, the device might consume significantly more current than the specified typical supply current. this is because of contentions among the internal nodes being affected by the hardware reset signal until they reach their final hardware reset state.
preliminary information motorola dsp56011 technical data sheet, rev. 1 4-7 design considerations host port considerations preliminary host port considerations careful synchronization is required when reading multi-bit registers that are written by another asynchronous system. this is a common problem when two asynchronous systems are connected. the situation exists in the host interface. the following paragraphs present considerations for proper operation. host programming considerations unsynchronized reading of receive byte registers ?hen reading receive byte registers, rxh or rxl, the host program should use interrupts or poll the rxdf flag which indicates that data is available. this assures that the data in the receive byte registers will be stable. overwriting transmit byte registers ?he host program should not write to the transmit byte registers, txh or txl, unless the txde bit is set, indicating that the transmit byte registers are empty. this guarantees that the transmit byte registers will transfer valid data to the hrx register. synchronization of status bits from dsp to host ?c, horeq , dma, hf3, hf2, trdy, txde, and rxdf status bits are set or cleared from inside the dsp and read by the host processor (refer to the user? manual for descriptions of these status bits). the host can read these status bits very quickly without regard to the clock rate used by the dsp, but the state of the bit could be changing during the read operation. generally, this is not a system problem, since the bit will be read correctly in the next pass of any host polling routine. however, if the host asserts hen for more than timing number 31, with a minimum cycle time of timing number 31 + 32, then these status bits are guaranteed to be stable. exercise care when reading status bits hf3 and hf2 as an encoded pair. if the dsp changes hf3 and hf2 from 00 to 11, there is a small probability that the host could read the bits during the transition and receive 01 or 10 instead of 11. if the combination of hf3 and hf2 has significance, the host could read the wrong combination. therefore, read the bits twice and check for consensus. overwriting the host vector ?he host program should change the host vector register only when the host command bit (hc) is clear. this change will guarantee that the dsp interrupt control logic will receive a stable vector. cancelling a pending host command exception ?he host processor may elect to clear the hc bit to cancel the host command exception request at any time before it is recognized by the dsp. because the host does not know exactly when the exception will be recognized (due to exception processing synchronization and pipeline delays), the dsp may execute the host
preliminary information 4-8 dsp56011 technical data sheet, rev. 1 motorola design considerations host port considerations preliminary command exception after the hc bit is cleared. for these reasons, the hv bits must not be changed at the same time that the hc bit is cleared. variance in the host interface timing ?he host interface (hi) may vary (e.g. due to the pll lock time at reset). therefore, a host which attempts to load (bootstrap) the dsp should first make sure that the part has completed its hi port programming (e.g., by setting the init bit in icr then polling it and waiting it to be cleared, then reading the isr or by writing the treq/rreq together with the init and then polling init, isr, and the horeq pin). dsp programming considerations synchronization of status bits from host to dsp ?ma, hf1, hf0, and hcp, htde, and hrdf status bits are set or cleared by the host processor side of the interface. these bits are individually synchronized to the dsp clock. (refer to the user? manual for descriptions of these status bits.) reading hf0 and hf1 as an encoded pair ?are must be exercised when reading status bits hf0 and hf1 as an encoded pair, (i.e., the four combinations 00, 01, 10, and 11 each have significance). a very small probability exists that the dsp will read the status bits synchronized during transition. therefore, hf0 and hf1 should be read twice and checked for consensus.
