DC Electrical Characteristics

Table 4 provides the recommended operating conditions for the MPC7448 part numbers described here.

NOTE

Table 4 describes the nominal operating conditions of the device. For

information on the operation of the device at supported derated core voltage

conditions, see Section 5.3, “Voltage and Frequency Derating.”

Notes:

1. These are the recommended and tested operating conditions. Some speed grades in addition 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, “Voltage and Frequency Derating,” is not guaranteed.

2. This voltage is the input to the filter discussed in Section 9.2.2, “PLL Power Supply Filtering,” in the hardware specifications

and not necessarily the voltage at the AVDD pin, which may be reduced from VDD by the filter.

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.

Effective for 1400 MHz devices with date code of 0613 and later; this includes all devices with the ‘PPC’ product code. VDD

and AVDD were specified at 1.1V ± 50 mV for 1400 MHz devices with date code 0612 and prior. See Section 11, “Part

Numbering and Marking,” for more information.
