Installation And Setup

The Motorola MPC500 Family companion power supply Power Oak (PC33394) is provided on

the EVB board. This device provides many features designed for automotive applications but

may also be useful for industrial or general purpose applications. See the PC33394 data sheet for

full description of features, operation, and capability.

The Power Oak provides a regulated switch mode power source for the 2.6V, 3.3V, and 5V sup-

plies on the EVB board. The basic application of the Power Oak provides the Reset signals,

back-up supplies for the KAPWR and IRAMSTBY to the MPC564, and the CAN A port trans-

ceiver. Many options are available on the board and some under software control via the MPC564

QSPI port to modify the Power Oak application.

The Power Port provides tap points for the power supplies and switched power outputs from the

Power Oak. Following is the Power Port pin assignment:

Table 2-1. Power Port Connections

Refer to Power Oak document for application of the provided power sources.

TB1, ON Option, and PWR

TB1 Provides main input power source access and the Power Oak VIGN input signal. The +VIN

and ground sources may be applied or tapped from the TB1 pin 2 and 3 connections respectfully.

TB1 pin 1 provides access the VIGN signal to the Power Oak, user should note ON jumper oper-

ation in the following text.

The ON jumper provides a constant enable to the VIGN signal so the Power Oak is enabled upon

power application. The ON option jumper may be removed to apply the VIGN signal externally

with a switch or other source. Basic operation of the VIGN signal is to apply +VIN to enable the
