Descriptions
The RFM210W/RFM217W devices are ultra low power, high performance, low-cost OOK stand-alone RF receiver for various 300 to 960 MHz wireless applications. The RFM210W covers the frequency range from 300 to 480MHz while the RFM217W covers the 300 to 960 MHz frequency range. They are part of the CMOSTEK NextGenRFTM family, which includes a complete line of transmitters, receivers and transceivers. An embedded EEPROM allows the frequency, symbol rate and other features to be programmed into the device using the CMOSTEK USB Programmer and RFPDK. Alternatively, in stock products of 433.92/868.35 MHz are available for immediate demands without the need of EEPROM programming. When the RFM210W/217W is always on, it consumes only 3.8 mA current while achieving -108 dBm receiving sensitivity. It consumes even less power when working in duty-cycle operation mode via the built-in sleep timer. The RFM210W/RFM217W receiver together with the RFM11x transmitter enables an ultra low cost RF link.
