QE Peripheral Module Quick Reference User Guide

A Compilation of Demonstration Firmware for QE Modules

This document is a brief description of the QE128 microcontroller unit (MCU) in an 8-bit version and

32-bit version. There is also useful information about core differences.

This document is a compilation of code examples and quick reference materials that have been created to

help users speed the development of their applications. Each section in this document contains an example

that works with an evaluation board (EVB) and Demo board with both 8-bit and 32-bit cores versions.

These examples were developed using CodeWarriorTM 6.0 version. Consult the device reference manual

for specific part information.

NOTE

• The provided examples were made to be used with the MC9S08QE128

and MCF51QE128 in an 80-pin and 64-bit package, but could be easily

migrated to a different QE device, pay attention to the used pins.

• All the example projects were developed in two different boards:

EVBQE128 STARTER KIT and DEMO board, no extra hardware is

needed except for the ACMP module, SPI, and IIC.

QE MCUs 8-bit and 32-bit Comparison

2.1 Overview

This is a brief explanation of MCU architectures. It has helpful informationabout cores, addressing modes

and exception processing. The intention of this section is to provide an overview of the S08 and V1 Core.

Further information can be found in reference manuals at www.freescale.com.

2.2 Cores Comparison

2.2.1 V1 core

The MCF51QE128, MCF51QE96, MCF51QE64 are members of the low-cost, low-power, high

performance ColdFire®V1 core (version 1) family of 32-bit MCUs. Figure 2-1 shows the ColdFire V1

core platform block diagram.

The ColdFire V1 core features are:

• Implements Instruction Set Revision C (ISA_C).

• Supports up to 30 peripheral interrupts and seven software interrupts.

• Built upon lowest-cost ColdFire V2 core microarchitecture.

• Two independent decoupled 2-stage pipelines.

• Debug architecture remapped into S08's single-pin BDM interface.
