PowerQUICC™ MPC8308_RDB User's

Guide

The MPC8308_RDB is a system featuring the

PowerQUICC™ processor, MPC8308. This low-cost,

high-performance system solution consists of a printed

circuit board (PCB) assembly plus a software board support

package (BSP) distributed in a CD image. This BSP enables

the fastest possible time-to-market for development or

integration of applications including printer engines,

broadband gateways, no-new-wires home adapters/access

points, and home automation boxes.

This document describes the hardware features of the board

including specifications, block diagram, connectors,

interfaces, and hardware straps. It also describes the board

settings and physical connections needed to boot the

MPC8308_RDB. Finally, it considers the software shipped

with the platform.

When you finish reading this document, you should:

•

be familiar with the board layout

•

understand the default board configuration and your

board configuration options

•

know how to get started and boot the board

•

know about the software and further documentation

that supports the board

Page 30: Getting Started
Getting Started supply voltage and IO supply voltages to be applied in any particular order. However, during the power ramp up, before the power supplies are stable, there may be an interval when the IO pins are actively driven. After the power is stable, as long as PORESET is asserted, most IO pins are three-stated. To minimize the time that IO pins are actively driven, apply core voltage before IO voltage and assert PORESET before the power supplies fully ramp up.
