Electrical and Thermal Characteristics
Figure 2 shows the allowable undershoot and overshoot voltage on the MPC755.
Figure 2. Overshoot/Undershoot Voltage
The MPC755 provides several I/O voltages to support both compatibility with existing systems and
migration to future systems. The MPC755 core voltage must always be provided at nominal 2.0 V (see
Table 3 for actual recommended core voltage). 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 Table 2. The
input voltage threshold 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 OVDD or L2OVDD power
pins.
Table 2 describes the input threshold voltage setting.
