Part Revision
1. Caution: The input threshold selection must agree with the OV
2. The input threshold settings above are different for all revisions prior to Rev. 2.8 (Rev. E). For more information, contact your

The PC755 provides several I/O voltages to support both compatibility with existing systems and
migration to future systems. The PC755 core voltage must always be provided at nominal 2.0V
(see
age). Voltage to the L2 I/Os and Processor Interface I/Os are provided through separate sets of
supply pins and may be provided at the voltages shown in
for each bus is selected by sampling the state of the voltage select pins BVSEL and L2VSEL
during operation. These signals must remain stable during part operation and cannot change.
The output voltage will swing from GND to the maximum voltage applied to the OV
power pins.
