ZigBee- Ready RF Transceiver Module CTL3585

1. General Description

The CTL3585 are compact surface mounted High Power Wireless RF Transceiver 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 size of CTL3514 is 19.2 x 16 x

2.8 mm and the size of CTL3585 is 23.5x16 x2.8mm.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. It contains 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.
