10 / 52 page  10 MPC7450 RISC Microprocessor Hardware Specifications MOTOROLA Electrical and Thermal Characteristics Table 2. Absolute Maximum Ratings1 Characteristic Symbol Maximum Value Unit Notes Core supply voltage VDD –0.3 to 1.95 V 4 PLL supply voltage AVDD –0.3 to 1.95 V 4 Processor bus supply voltage BVSEL = 0 OVDD –0.3 to 1.95 V 3, 6 BVSEL = HRESET or OVDD OVDD –0.3 to 2.7 V 3, 7 L3 bus supply voltage L3VSEL = ¬HRESET GVDD –0.3 to 1.65 V 3, 8 L3VSEL = 0 GVDD –0.3 to 1.95 V 3, 9 L3VSEL = HRESET or GVDD GVDD –0.3 to 2.7 V 3, 10 Input voltage Processor bus Vin –0.3 to OVDD + 0.3 V 2, 5 L3 bus Vin –0.3 to GVDD + 0.3 V 2, 5 JTAG signals Vin –0.3 to OVDD + 0.3 V Storage temperature range Tstg –55 to 150 °C Notes: 1. Functional and tested operating conditions are given in Table 4. Absolute maximum ratings are stress ratings only, and functional operation at the maximums is not guaranteed. Stresses beyond those listed may affect device reliability or cause permanent damage to the device. 2. Caution: Vin must not exceed OVDD or GVDD by more than 0.3 V at any time including during power-on reset. 3. Caution: OVDD/GVDD must not exceed VDD/AVDD by more than 2.0 V at any time including during power-on reset. 4. Caution: VDD/AVDD must not exceed OVDD/GVDD by more than 0.4 V at any time including during power-on reset. 5. Vin may overshoot/undershoot to a voltage and for a maximum duration as shown in Figure 2. 6. BVSEL must be set to 0, such that the bus is in 1.8 V mode. 7. BVSEL must be set to HRESET or 1, such that the bus is in 2.5 V mode. 8. L3VSEL must be set to ¬HRESET (inverse of HRESET), such that the bus is in 1.5 V mode. 9. L3VSEL must be set to 0, such that the bus is in 1.8 V mode. 10. L3VSEL must be set to HRESET or 1, such that the bus is in 2.5 V mode. Freescale Semiconductor, Inc.
