Electrical and Thermal Characteristics
Table 4 provides the recommended operating conditions for the MPC7447A.
NOTE
Table 4 describes the nominal operating conditions of the device. For
information regarding the operation of the device at supported derated core
Table 5 provides the package thermal characteristics for the MPC7447A.

Notes:
1. Caution: The input threshold selection must agree with the OVDD voltages supplied. See notes in Table 2.
2. If used, pull-down resistors should be less than 250
Ω.

Notes:
1. These are the recommended and tested operating conditions. In addition, these devices also support voltage
derating; see Section 5.3, “Voltage and Frequency Derating.” Proper device operation outside of these conditions
and those specified in Section 5.3 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.
3. VDD and AVDD may be reduced in order to reduce power consumption if further maximum core frequency
constraints are observed. See Section 5.3, “Voltage and Frequency Derating,” for specific information.
