EM9209- Proprietary Protocols

High Sensitivity, 1.5-72kbps, 2.4GHz FSK Transceiver - Ultra-Low Power

General Description

The EM9209 is a 1.5kbps to 72kbps low-power, low voltage, single chip 2.4GHz ISM band RF transceiver ideal for battery operated wireless applications such as wireless sensors and control, gaming, human interface devices, and security networks.
The EM9209's built-in custom low power micro-controller supports the proprietary wireless protocol links in the license-free 2.4000GHz to 2.4835GHz ISM band. It includes a low-IF receiver architecture and uses FSK modulation. A SPI interface provides a simple control of the baseband using an external host controller.
The EM9209 provides two communication modes with normal or high sensitivity and programmable bit rate from 1.5kbps to 72kbps.
The EM9209 provides a divided clock output programmable at either 32.5kHz, 325kHz or 3.25MHz to drive external micro-controllers time reference.
