signal/pin descriptions pll and clock motorola dsp56002/d, rev. 3 1-5 pll and clock table 1-4 pll and clock signals signal name signal type state during reset signal description extal input input external clock/crystal input this input connects the internal oscillator input to an external crystal or to an external oscillator. xtal output chip- driven crystal output this output connects the internal crystal oscillator output to an external crystal. if an external oscillator is used, xtal should be left unconnected. ckout output chip- driven pll output clock when the pll is enabled and locked, this signal provides a 50% duty cycle output clock signal synchronized to the internal processor clock. when the pll is enabled and the multiplication factor is less than or equal to 4, then ckout is synchronized to extal. when the pll is disabled, the output clock at ckout is derived from, and has the same frequency and duty cycle as, extal. note: for information about using the pll multiplication factor, see the dsp56002 users manual . ckp input input pll output clock polarity control the value of this signal at reset defines the polarity of the ckout output relative to extal. if ckp is pulled low by connecting through a resistor to ground, ckout and extal have the same polarity. pulling ckp high by connecting it through a resistor to v cc causes ckout and extal to be inverse polarities. the polarity of ckout is latched at the end of reset; therefore, any changes to ckp after deassertion of reset do not affect ckout polarity. pcap input/ output indeter- minate pll capacitor this signal is used to connect the required external filter capacitor to the pll filter. connect one end of the capacitor to pcap and the other to v ccp . the value of the capacitor is specified in section 2 of this data sheet.
1-6 dsp56002/d, rev. 3 motorola signal/pin descriptions pll and clock pinit input input pll initialization source the value of this signal at reset defines the value written into the pll enable (pen) bit in the pll control register. if pinit is pulled high during reset, the pen bit is written as a 1, enabling the pll and causing the dsp internal clocks to be derived from the pll vco. if pinit is pulled low during reset, the pen bit is written as a 0, disabling the pll and causing dsp internal clocks to be derived from the clock connected to extal. pen is written only at the deassertion of reset and; therefore, the value of pinit is ignored after that time. plock output indeter- minate phase and frequency lock this output is generated by an internal phase detector circuit. this circuit drives the output high when: ? the pll is disabled (the output clock is extal and is therefore in phase with itself), or ? the pll is enabled and is locked onto the proper phase (based on the ckp value) and frequency of extal. the circuit drives the output low (deasserted) whenever the pll is enabled, but has not locked onto the proper phase and frequency. note: plock is a reliable indicator of the pll lock state only after the chip has exited the reset state. during hardware reset, the plock state is determined by pinit and the current pll lock condition. table 1-4 pll and clock signals (continued) signal name signal type state during reset signal description

(data is clocked into the once 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. when it is an output, this signal works with the os0 signal to provide information about the chip status. the dsck/os1 signal is an output when the chip is not in debug mode. note: connect an external pull-down resistor to this signal.

motorola dsp56002/d, rev. 3 2-1 section 2 specifications general characteristics the dsp56002 is fabricated in high-density hcmos with ttl compatible inputs and outputs. 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 maximum value for a specification will never occur in the same device that has a minimum 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 ).

4-2 dsp56002/d, rev. 3 motorola design considerations heat dissipation 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 ) as determined by a thermocouple, the thermal resistance is computed using the value obtained by the equation (t j e 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 e 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. note: table 2-2 thermal characteristics on page 2-2 contains the package thermal values for this chip.
design considerations electrical design considerations motorola dsp56002/d, rev. 3 4-3 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 0.1 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 inch 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 rd , wr , irqa , irqb , nmi , hen , and hack pins. 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. take special care to minimize noise levels on the pll supply pins (both v cc and gnd). 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 ).
4-4 dsp56002/d, rev. 3 motorola design considerations power consumption power consumption power dissipation is a key issue in portable dsp applications. the following describes some factors which affect current consumption. current consumption is described by the formula: equation 3: where: c = node/pin capacitance v = voltage swing f = frequency of node/pin toggle for example, for an address pin loaded with a 50 pf capacitance and operating at 5.5 v with a 40 mhz clock, toggling at its maximum possible rate (which is 10 mhz), the current consumption is: equation 4: the maximum internal current value (i cci -max), reflects the maximum i cc expected when running the code given below. this represents typical internal activity, and is included as a point of reference. some applications may consume more or less current depending on the code used. the typical internal current value (i cci -typ) reflects what is typically seen when running the given code. the following steps are recommended for applications requiring very low current consumption: 1. minimize external memory accesses; use internal memory accesses instead. 2. minimize the number of pins that are switching. 3. minimize the capacitive load on the pins. 4. connect the unused inputs to pull-up or pull-down resistors. i cvf = i5010 12 C 5.5 10 10 6 2.75ma ==

4-6 dsp56002/d, rev. 3 motorola design considerations host port considerations host port considerations careful synchronization is required when reading multibit 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 when reading receive byte registers (rxh, rxm, and rxl) the host programmer should use interrupts or poll the rxdf flag that indicates that data is available. this assures that the data in the receive byte registers will be stable. overwriting transmit byte registers the host programmer should not write to the transmit byte registers (txh, txm, and 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 hc, hreq, dma, hf3, hf2, trdy, txde, and rxdf status bits are set or cleared from inside the dsp and read by the host processor. the host can read these status bits very quickly without regard to the clock rate used by the dsp, but the possibility exists that the state of the bit could be changing during the read operation. this is generally not a system problem, since the bit will be read correctly in the next pass of any host polling routine. note: refer to dsp56002 users manual sections describing the i/o interface and host/dma interface programming model for descriptions of these status bits. overwriting the host vector the host programmer should change the host vector register only when the host command bit (hc) is clear. this change guarantees that the dsp interrupt control logic will receive a stable vector.
design considerations host port considerations motorola dsp56002/d, rev. 3 4-7 cancelling a pending host command exception the 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 command exception after the hc bit is cleared. for these reasons, the hv bits must not be changed at the same time the hc bit is cleared. variance in the hi timing hi timing may vary during initial startup during the time after reset before the pll locks. therefore, before a host attempt to load (i.e., bootstrap) the dsp, the host should first make sure that the hi port programming has been completed. the following steps can be used to ensure that the programming is complete: 1. set the init bit in the icr 2. poll the init bit until it is cleared. 3. read the isr. an alternate method is: 1. write the treq/rreq together with init. 2. poll init, isr, and the hreq pin. dsp programming considerations synchronization of status bits from host to dsp dma, 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. note: refer to dsp56002 users manual sections describing the i/o interface and host/dma interface programming model for descriptions of these status bits. reading hf0 and hf1 as an encoded pair a potential problem exists 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. the solution to this potential problem is to read the hf0 and hf1 bits twice and check for consensus.
