Electrical and Thermal Characteristics
Figure 2
The MPC7448 provides several I/O voltages to support both compatibility with existing systems and
migration to future systems. The MPC7448 core voltage must always be provided at the nominal voltage
(see
select pins at the negation of the signal HRESET. The output voltage will swing from GND to the
maximum voltage applied to the OV
Because these settings may change in future products, it is recommended that BVSEL[0:1] be configured
using resistor options, jumpers, or some other flexible means, with the capability to reconfigure the
termination of this signal in the future, if necessary.

4). The input voltage threshold for each bus is selected by sampling the state of the voltage
Notes:
1. Caution: The I/O voltage mode selected must agree with the OV
2. If used, pull-down resistors should be less than 250 Ω.
3. The pin configuration used to select 1.8V mode on the MPC7448 is not compatible
4. The pin configuration used to select 2.5V mode on the MPC7448 is fully compatible
