12 / 64 page ![]() MPC7455 RISC Microprocessor Hardware Specifications, Rev. 4.1 12 Freescale Semiconductor Electrical and Thermal Characteristics Table 4 provides the recommended operating conditions for the MPC7455. Table 4. Recommended Operating Conditions 1 Characteristic Symbol Recommended Value Unit Notes Min Max Core supply voltage VDD 1.3 V ± 50 mV V PLL supply voltage AVDD 1.3 V ± 50 mV V 2 Processor bus supply voltage BVSEL = 0 OVDD 1.8 V ± 5% V BVSEL = HRESET or OVDD OVDD 2.5 V ± 5% V L3 bus supply voltage L3VSEL = 0 GVDD 1.8 V ± 5% V L3VSEL = HRESET or GVDD GVDD 2.5 V ± 5% V L3VSEL = ¬HRESET GVDD 1.5 V ± 5% V Input voltage Processor bus Vin GND OVDD V L3 bus Vin GND GVDD V JTAG signals Vin GND OVDD V Die-junction temperature Tj 0105 °C Notes: 1. These are the recommended and tested operating conditions. Proper device operation outside of these conditions is not guaranteed. 2. This voltage is the input to the filter discussed in Section 9.2, “PLL Power Supply Filtering,” and not necessarily the voltage at the AVDD pin which may be reduced from VDD by the filter. |
