Electrical and Thermal Characteristics
Table 4 provides the recommended operating conditions for the MPC7450.
Table 5 provides the package thermal characteristics for the MPC7450.
Core supply voltage
PLL supply voltage
Processor bus supply voltage
L3 bus supply voltage
Input voltage
Die-junction temperature
Notes:
1. These are the recommended and tested operating conditions. Proper device operation outside of these conditions
2. This voltage is the input to the filter discussed in Section 1.9.2, “PLL Power Supply Filtering” and not necessarily
3. 1.6 V nominal. Operation at core voltages up to 1.8 V is supported, but the power consumption given in Table 7
