1. General

The CTL357x RF Transceiver Module is comp

Description

act surface mounted Module specially designed for
Ember ZigBee™ protocol stack for wireless networks, EmberZNet, based on IEEE 802.15.4
standard in the 2.4GHz world-wide ISM band. The complete module is only 32.4 x 25.4 x 4.1 mm. It
integrated a 2.4GHz, IEEE 802.15.4-2003 compliant transceiver with a 32-bit network processor
(ARM Cortex-M3 Processor) to run EmberZNet. They contain embedded Flash and integrated RAM
for program and data storage. It utilizes the non-intrusive SIF module for powerful software
debugging and programming of the network processor.
