About This Book

This manual describes Freescale’s TWR-KW2xDxxx development platform hardware. The 
TWR-KW2xDxxx is an IEEE® 802.15.4 compliant evaluation environment based on the Freescale 
MKW2xDxxx device. The MKW2xDxxx family is Freescale's latest generation ZigBee™ platform, 
which incorporates a complete low power 2.4 GHz radio frequency transceiver and a Kinetis family low 
power, mixed-signal ARM Cortex™-M4 MCU into a single package. This family of products is targeted 
to meet the higher performance requirements of ZigBee Pro and ZigBee IP based applications, especially 
Smart Energy and Commercial Building Automation. This product is a cost-effective solution that matches 
or exceeds competitive solutions.

Audience

This manual is intended for system designers.
