Electrical and Thermal Characteristics
The MPC7457 provides several I/O voltages to support both compatibility with existing systems and
migration to future systems. The MPC7457 core voltage must always be provided at nominal 1.3 V (see
Table 4
provided through separate sets of supply pins and may be provided at the voltages shown in
input voltage threshold for each bus is selected by sampling the state of the voltage select pins at the
negation of the signal HRESET. The output voltage will swing from GND to the maximum voltage applied
to the OV

Notes:
1. Not implemented on MPC7447.
2. Caution: The input threshold selection must agree with the OV
3. If used, pull-down resistors should be less than 250 Ω.
4. Applicable to L3 bus interface only. ¬HRESET is the inverse of HRESET.
