motorola mpc826xa (hip4) family hardware speci?ations 13 preliminary?ubject to change without notice electrical and thermal characteristics all output pins on the mpc826xa have fast rise and fall times. printed circuit (pc) trace interconnection length should be minimized in order to minimize overdamped conditions and re ections caused by these fast output switching times. this recommendation particularly applies to the address and data buses. maximum pc trace lengths of six inches are recommended. capacitance calculations should consider all device loads as well as parasitic capacitances due to the pc traces. attention to proper pcb layout and bypassing becomes especially critical in systems with higher capacitive loads because these loads create higher transient currents in the v cc and gnd circuits. pull up all unused inputs or signals that will be inputs during reset. special care should be taken to minimize the noise levels on the pll supply pins. table 7 provides preliminary, estimated power dissipation for various con gurations. note that suitable thermal management is required for conditions above p d = 3w (when the ambient temperature is 70 ? c or greater) to ensure the junction temperature does not exceed the maximum speci ed value. also note that the i/o power should be included when determining whether to use a heat sink. 1.2.4 ac electrical characteristics the following sections include illustrations and tables of clock diagrams, signals, and cpm outputs and inputs for the 66 mhz mpc826xa device. note that ac timings are based on a 50-p f load. typical output buffer impedances are shown in table 8. table 7. estimated power dissipation for various con?urations 1 1 test temperature = room temperature (25 ? c) bus (mhz) cpm multiplier core cpu multiplier cpm (mhz) cpu (mhz) p int (w) 2 2 p int = i dd x v dd watts vddl 1.8 volts vddl 2.0 volts nominal maximum nominal maximum 66.66 2 3 133 200 1.2 2 1.8 2.3 66.66 2.5 3 166 200 1.3 2.1 1.9 2.3 66.66 3 4 200 266 2.3 2.9 66.66 3 4.5 200 300 2.4 3.1 83.33 2 3 166 250 2.2 2.8 83.33 2 3 166 250 2.2 2.8 83.33 2.5 3.5 208 291 2.4 3.1 table 8. output buffer impedances 1 1 these are typical values at 65? c. the impedance may vary by ?5% with process and temperature. output buffers typical impedance ( ? ) 60x bus 40 local bus 40 memory controller 40 parallel i/o 46 pci 25
