本书主要讲述Freescale符合IEEETM 802.15.4标准的软件，即MAC/PHY软件。Freescale 802.15.4 MAC/PHY软件使用在短距离、低功耗，应用于工业、科学和医疗（ISM）研究领域的2.4GHz的收发器的产品家族中，下面是涉及的有关的产品信息：

• Freescale MC1319x和MC1320x系列，它的设计使用的MCU是HCS08系列的。

• Freescale MC1320x，它的设计基于MCS08QE128的MCU。

• Freescale MC1321x家族，它的设计是将一个低功耗的2.4G的收发器和一个8位的微控制器组合在一起，采用LGA的单封装结构。

• Freesacle MC1322x Platform-In-Package，它的设计是将一个低功耗的2.4G的收发器和一个32位的ARM7微控制器组合在一个，采用LGA单封装结构。

全书涉及的收发器指的是MC1319x，MC1320x或集成在一起的MC1321x或MC1322x。

本书适用于802.15.4MAC应用软件开发者。-This manual describes Freescale’s IEEE™　802.15.4 Standard compliant MAC/PHY software. The Freescale 802.15.4 MAC/PHY software is designed for use with the following families of short range, low power, 2.4 GHz Industrial, Scientific, and Medical (ISM) band transceivers:

• Freescale MC1319x and MC1320x families, designed for use with the HCS08 Family of MCUs.

• Freescale MC1320x, designed for use with the MCS08QE128 MCU.

• Freescale MC1321x family, that incorporates a low power 2.4 GHz radio frequency transceiver and an 8-bit microcontroller into a single LGA package.

• Freescale MC1322x Platform-In-Package, that combines a low power 2.4 GHz frequency transceiver and a 32-bit ARM7 microcontroller into a single LGA package.

Throughout this manual, the term transceiver refers to either the MC1319x, MC1320x, or the internal counterpart inside the MC1321x or MC1322x.

This document is intended for 802.15.4 MAC application developers.
