MPC7457 Hardware Specification Addendum for the MPC74n7RXnnnnNx Series, Rev. 3 2 Freescale Semiconductor General Parameters Table 7 provides the power consumption for the MPC7457 part numbers described herein.

These values apply for all valid processor bus and L3 bus ratios. The values do not include I/O supply power (OVDD and GVDD) or PLL supply power (AVDD). OVDD and GVDD power is system dependent, but is typically <5% of V DD power. Worst case power consumption for AVDD < 3 mW. 2. Maximum power is the maximum measured at nominal VDD and maximum operating junction temperature (see Table 4) while running an entirely cache-resident, contrived sequence of instructions which keep all the execution units maximally busy. 3. Typical power is an average value measured at the nominal recommended VDD (see Table 4) and 65C while running the Dhrystone 2.1 benchmark and achieving 2.3 Dhrystone MIPs/MHz. 4. Doze mode is not a user-definable state; it is an intermediate state between full-power and either nap or sleep mode. As a result, power consumption for this mode is not tested.

All input specifications are measured from the midpoint of the signal in question to the midpoint of the rising edge of the input SYSCLK. All output specifications are measured from the midpoint of the rising edge of SYSCLK to the midpoint of the signal in question. All output timings assume a purely resistive 50- load. Input and output timings are measured at the pin; time-of-flight delays must be added for trace lengths, vias, and connectors in the system. 2. The symbology used for timing specifications herein follows the pattern of t(signal)(state)(reference)(state) for inputs and t(reference)(state)(signal)(state) for outputs. For example, tIVKH symbolizes the time input signals (I) reach the valid state (V) relative to the SYSCLK reference (K) going to the high (H) state or input setup time. And tKHOV symbolizes the time from SYSCLK(K) going high (H) until outputs (O) are valid (V) or output valid time. Input hold time can be read as the time that the input signal (I) went invalid (X) with respect to the rising clock edge (KH) (note the position of the reference and its state for inputs) and output hold time can be read as the time from the rising edge (KH) until the output went invalid (OX). 3. tsysclk is the period of the external clock (SYSCLK) in ns. The numbers given in the table must be multiplied by the period of SYSCLK to compute the actual time duration (in ns) of the parameter in question. 4. According to the bus protocol, TS is driven only by the currently active bus master. It is asserted low then precharged high before returning to high impedance. The nominal precharge width for TS is 0.5 x tSYSCLK, that is, less than the minimum tSYSCLK period, to ensure that another master asserting TS on the following clock will not contend with the precharge. Output valid and output hold timing is tested for the signal asserted. Output valid time is tested for precharge.The high-impedance behavior is guaranteed by design. 5. Guaranteed by design and not tested. 6. According to the bus protocol, ARTRY can be driven by multiple bus masters through the clock period immediately following AACK. Bus contention is not an issue because any master asserting ARTRY will be driving it low. Any master asserting it low in the first clock following AACK will then go to high impedance for one clock before precharging it high during the second cycle after the assertion of AACK. The nominal precharge width for ARTRY is 1.0 tSYSCLK; that is, it should be high impedance before the first opportunity for another master to assert ARTRY. Output valid and output hold timing is tested for the signal asserted.The high-impedance behavior is guaranteed by design. 7. According to the MPX bus protocol, SHD0 and SHD1 can be driven by multiple bus masters beginning the cycle of TS. Timing is the same as ARTRY, that is, the signal is high impedance for a fraction of a cycle, then negated for up to an entire cycle (crossing a bus cycle boundary) before being three-stated again. The nominal precharge width for SHD0 and SHD1 is 1.0 tSYSCLK. The edges of the precharge vary depending on the programmed ratio of core to bus (PLL configurations). 8. BMODE[0:1] and BVSEL are mode select inputs and are sampled before and after HRESET negation. These parameters represent the input setup and hold times for each sample. These values are guaranteed by design and not tested. These inputs must remain stable after the second sample.
