Freescale Semiconductor
Electrical and Thermal Characteristics
Figure 2 shows the undershoot and overshoot voltage on the MPC7448.
Figure 2. Overshoot/Undershoot Voltage
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 Table 4). 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 power pins. Table 3 provides the input threshold voltage settings.
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.

Notes:
1. Caution: The I/O voltage mode selected must agree with the OVDD voltages
supplied. See Table 4.
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
with the pin configuration used to select 1.8V mode on the MPC7447A and earlier
devices.
4. The pin configuration used to select 2.5V mode on the MPC7448 is fully compatible
with the pin configuration used to select 2.5V mode on the MPC7447A and earlier
devices.
