MPC7400 RISC Microprocessor Hardware Specications
PRELIMINARY—SUBJECT TO CHANGE WITHOUT NOTICE
Electrical and Thermal Characteristics
4. Capacitance is periodically sampled rather than 100% tested.
5. The leakage is measured for nominal OVdd and Vdd, or both OVdd and Vdd must vary in the same direction (for example,
both OVdd and Vdd vary by either +5% or -5%).
Table 7 provides the power consumption for the MPC7400.
1.4.2 AC Electrical Characteristics
This section provides the AC electrical characteristics for the MPC7400. After fabrication, functional parts
are sorted by maximum processor core frequency as shown in Section 1.4.2.1, “Clock AC Specications,”
and tested for conformance to the AC specications for that frequency. The processor core frequency is
determined by the bus (SYSCLK) frequency and the settings of the PLL_CFG[0–3] signals. Parts are sold
by maximum processor core frequency; see Section 1.10, “Ordering Information.”

Notes:
1. These values apply for all valid processor bus and L2 bus ratios. The values do not include
I/O Supply Power (OVdd and L2OVdd) or PLL/DLL supply power (AVdd and
L2AVdd). OVdd and L2OVdd power is system dependent, but is typically <10% of Vdd
power. Worst case power consumption for AVdd = 15 mw and L2AVdd = 15 mW.
2. Maximum power is measured at Vdd = 1.9V while running an entirely cache-resident,
contrived sequence of instructions which keep the execution units, including AltiVec,
maximally busy.
3. Typical power is an average value measured at Vdd = AVdd = L2AVdd = 1.8V, OVdd =
L2OVdd = 3.3V in a system while running a codec application that is AltiVec intensive.
4. These values include the use of AltiVec. Without AltiVec operation, estimate a 25%
decrease.
