FACT SHEET | EM9209 Subject to change without notice Version 3.0, 13-Oct-14 Copyright © 2014, EM Microelectronic-Marin SA www.emmicroelectronic.com High Sensitivity, Long Range, 1.5-72kbps, 2.4GHz FSK Transceiver General Description Features 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. I Low Voltage: · 1.9V to 3.6V battery operation 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 for Long Range links 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. I Low Power: · 7mA in RX normal sensitivity mode (NS) · 8mA in RX high sensitivity mode (HS) · TX Mode: 11mA @-1dBm, 36mA @+10dBm · <150µA in Stand-by Mode · <10nA in Power Down Mode I High Performance: · -115dBm sensitivity at 1.5kbps · +10dBm maximum received input signal · Programmable output power from -20dBm to +10dBm I Ultra compact radio design with low BOM cost: · COB with 4mm x 4mm footprint I Operating Temperature: -40°C to +85°C Applications I Direct antenna interface (200 Ω differential) I Remote sensing and control I Low-cost 26MHz crystal oscillator, frequency tolerance over temperature and aging of ±20ppm, with adjusted initial value I Wireless mice, keyboards, toys etc… I Wireless watch sensors, sports equipment I Alarm and security systems Simplified Application Schematic I Flexible interface: · SPI interface for microcontrollers · Fully programmable link layer · External PA and LNA control signal available on 2 pads SCK SS MOSI MISO VSS_DIG VSS_DIG DIV_CK VSS_ISO VSS_ISO EM9209 EN_REG XOUT MLF24 4x4mm VSS_SYNTH XIN VDD_SYNTH VSS_RXTX VSS_RXTX VBAT ANTN ANTP VDD_RXTX TX_ON VPROG RX_ON EN_REG VSS_DIG IRQ VSS_DIG MISO MOSI SS SCK Host Controller IRQ VDD_ SYNTH VSS_ SYNTH VDD_ RXTX VSS_ RXTX XOUT XIN EM9209 DIV_CK VSS_ISO Typical Configuration VPROG TX_ON RX_ON ANTP ANTN VSS_ RXTX VBAT I Available as die or in MLF24 4x4mm package
