preliminary motorola dsp56652 technical data sheet 2-1 section 2 specifications general characteristics the dsp56652 is fabricated in high-density cmos. the dsp56652 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. 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 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 ).

preliminary motorola dsp56652 technical data sheet 4-1 section 4 design considerations heat dissipation 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; ninety percent 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. 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 t j t a p d r q ja () + = r q ja r q jc r q ca + =
preliminary 4-2 dsp56652 technical data sheet 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 - 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, this 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. note: table 2-2 on page 2-2 of this document contains the package thermal values for this chip.
dsp56652 electrical design considerations preliminary motorola dsp56652 technical data sheet 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 r/w , dsp_irq , and int0eint7 signals. 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 ).
