The RFM64W is a low cost single-chip transceiver operating in the frequency ranges from 300MHz to 510MHz. The RFM64W is optimized for very low power consumption (3mA in receiver mode). It incorporates a baseband modem with data rates up to 150 kb/s. Data handling features include a sixty-four byte FIFO, packet handling, automatic CRC generation and data whitening. Its highly integrated architecture allows for minimum external component count whilst maintaining design flexibility. All major RF communication parameters are programmable and most of them may be dynamically set. It complies with European (ETSI EN 300-220 V2.1.1) and North American (FCC part15.247 and 15.249) regulatory standards.
