MPC7410 RISC Microprocessor Hardware Specifications
PRELIMINARY—SUBJECT TO CHANGE WITHOUT NOTICE
Electrical and Thermal Characteristics
Figure 2. Overshoot/Undershoot Voltage
The MPC7410 provides several I/O voltages to support both compatibility with existing systems and
migration to future systems. The MPC7410 “core” voltage must always be provided at nominal voltage (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 at the
negation of the signal HRESET. The output voltage will swing from GND to the maximum voltage applied
to the OVdd or L2OVdd power pins.
Table 3 provides the recommended operating conditions for the MPC7410.

Notes:
1. Caution: The input threshold selection must agree with the OVdd/L2OVdd voltages supplied.
2. To select the 2.5-V threshold option, BVSEL and/or L2VSEL should be tied to HRESET so that the two signals
change state together. This is the preferred method for selecting this mode of operation.
3. To overcome the internal pull-up resistance, a pull-down resistance less than 250 ohms should be used.
4. Default voltage setting if left unconnected (internal pulled-up).
