14 / 68 page  MPC7457 RISC Microprocessor Hardware Specifications, Rev. 5 14 Freescale Semiconductor Electrical and Thermal Characteristics Table 7 provides the power consumption for the MPC7457. Output high voltage, IOH = –5 mA 1.5 VOH OVDD/GVDD – 0.45 — V 6 1.8 OVDD/GVDD – 0.45 — V 2.5 1.8 — V Output low voltage, IOL = 5 mA 1.5 VOL — 0.45 V 6 1.8 — 0.45 V 2.5 — 0.6 V Capacitance, Vin = 0 V, f = 1 MHz L3 interface — Cin — 9.5 pF 5 All other inputs — 8.0 Notes: 1. Nominal voltages; see Table 4 for recommended operating conditions. 2. For processor bus signals, the reference is OVDD while GVDD is the reference for the L3 bus signals. 3. Excludes test signals and IEEE 1149.1 boundary scan (JTAG) signals. 4. The leakage is measured for nominal OVDD/GVDD and VDD, or both OVDD/GVDD and VDD must vary in the same direction (for example, both OVDD and VDD vary by either +5% or –5%). 5. Capacitance is periodically sampled rather than 100% tested. 6. Applicable to L3 bus interface only. Table 7. Power Consumption for MPC7457 Processor (CPU) Frequency Unit Notes 867 MHz 1000 MHz 1200 MHz 1267 MHz Full-Power Mode Typical 14.8 15.8 17.5 18.3 W 1, 2 Maximum 21.0 22.0 24.2 25.6 W 1, 3 Nap Mode Typical 5.2 5.2 5.2 5.2 W 1, 2 Sleep Mode Typical 5.1 5.1 5.1 5.1 W 1, 2 Table 6. DC Electrical Specifications (continued) At recommended operating conditions. See Table 4. Characteristic Nominal Bus Voltage 1 Symbol Min Max Unit Notes |
