Product Overview

RFM219B is a low power, high performance, OOK, (G) FSK RF receiver module which suitable for all kinds of 127 to 1020 MHz wireless applications. RFM219B is highly integrated, which simplifies the peripheral materials that needed in system design. It supports a variety of packet formats and codec methods, and can flexibly meet the needs of various applications for different packet formats and e codec. Also, the RFM219B module can support 64-byte Rx FIFO, the GPIO and interrupt configuration, Duty-Cycle running mode, RSSI detection, low voltage detection, low consumption timing out out wake-up, manual fast frequency hopping, static noise output and so on, which making the application designs more flexible thus to achieve product differentiation design. RFM219B works from 1.8 V to 3.6V. With -120dBm sensitivity and current consumption of only 8.5 mA, which combined with Duty-Cycle mode, so the receiving power of chips can be further reduced.
