RFM219S
RF receiving module
RFM219S is an ultra low power, high-performance (G) FSK/OOK modulation wireless receiver module that can flexibly modify frequencies in the range of 300-960 MHz. RFM219S belongs to the HOPERF NextGenRFTM series (which includes transmitters, receivers, and transceivers). All parameters can be written offline through EEPROM programming or written online through registers. The modification file written to the register will be generated by RFPDK. The working voltage of RFM219S is 1.8-3.6V, and the current under continuous operation is only 5.7 mA. The receiving sensitivity reaches -109 dBm (FSK modulation, rate 9.6 ksps, frequency 868.35 MHz), and the sleep current is only 60 nA, effectively extending the battery life. The module supports automatic data unpacking, 32 byte FIFO, Manchester encoding and whitening of received data. In addition to demodulating data and outputting synchronous clocks, RFM219S can also output power on reset, system clock, and two configurable interrupt reminders. The RFM219S receiver paired with the CMT211xA transmitter has stronger RF performance.
