CT-EM2506 ZigBee Ready RF Transceiver Modules
ZigBee- Ready SoC RF Transceiver Modules
1. General Description
The CT-EM2506 SoC RF Transceiver Modules is a compact surface mounted
module specially designed for Ember’s ZigBee™ protocol stack for wireless networks,
EmberZNet, based on IEEE 802.15.4 standard in the 2.4GHz world-wide ISM band. It
provides 16 channels and compliant PHY and MAC layers. The complete module is
only 25.4 x 32.4 x 4.1mm. They both integrate a 2.4GHz, IEEE 802.15.4-compliant
transceiver with a 16-bit XAP2b microprocessor and a FEM. They consist of
integrated Flash and RAM memory and peripherals. A number of peripherals such as
GPIO, UART, SPI, I2C, ADC, and general purpose timers are integrated to support
user-defined applications.
