RFM219B-315S2

The RFM219B is an ultra-low power, high performance product for a wide range of 127 to 1020 MHz wireless applications
OOK, (G)FSK radio frequency receiver. The RFM219B is highly integrated and simplifies the peripheral materials required in the system design. It supports a variety of packet formats and codec modes, and can flexibly meet the needs of various applications for different packet formats and codec. In addition, the RFM219B also supports 64-byte Rx FIFO, rich GPIO and interrupt configuration, Duty Cycle
Operation mode, channel listening, high-precision RSSI, low voltage detection, power-on reset, low frequency clock output, manual fast frequency hopping, noise suppression output and other functions make the application design more flexible and realize product differentiation design. The RFM219B operates from 1.8V to 3.6V. With only 8.5mA of current consumed when reaching -120dBm sensitivity, the ultra-low power receiving mode can further reduce the chip's receiving power consumption.
