CT-EM2606 ZigBee Ready RF Transceiver Modules

ZigBee- Ready RF Transceiver Modules

1. General Description

The CT-EM2606 RF Transceiver Modules is compact surface mounted modules 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 25.4 x 32.3 x 4mm .They both integrate a 2.4GHz, IEEE 802.15.4-compliant
transceiver with a 16-bit network processor (XAP2b core) 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.
