Electrical and Thermal Characteristics
1.5.2
AC Electrical Characteristics
This section provides the AC electrical characteristics for the MPC7457. After fabrication, functional parts
are sorted by maximum processor core frequency as shown in Section 1.5.2.1, “Clock AC Specifications,”
and tested for conformance to the AC specifications for that frequency. The processor core frequency is
determined by the bus (SYSCLK) frequency and the settings of the PLL_CFG[0:4] signals. Parts are sold
by maximum processor core frequency; see Section 1.11, “Ordering Information.”
1.5.2.1
Clock AC Specifications
Table 8 provides the clock AC timing specifications as defined in Figure 6and represents the tested
operating frequencies of the devices. The maximum system bus frequency, fSYSCLK, given in Table 8 is
considered a practical maximum in a typical single-processor system. The actual maximum SYSCLK
frequency for any application of the MPC7457 will be a function of the AC timings of the MPC7457, the
AC timings for the system controller, bus loading, printed-circuit board topology, trace lengths, and so forth,
and may be less than the value given in Table 8.

Notes:
1. 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 VDD
power. Worst case power consumption for AVDD < 3 mW.
2. Typical power is an average value measured at the nominal recommended VDD (see Table 4) and 65°C while
running the Dhrystone 2.1 benchmark and achieving 2.3 Dhrystone MIPs/MHz.
3. Maximum power is the average 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.
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.
