The MRF89XA is a single chip, multi-channel FSK/OOK transceiver capable of operating in the 863-870 MHz and 902-928 MHz license-free ISM frequency bands, as well as the 950-960 MHz frequency band. The low-cost MRF89XA is optimized for very low power consumption (3 mA in Receiver mode). It incorporates a baseband modem with data rates up to 200 kb/s. Data handling features include a 64-byte FIFO, packet handling, automatic CRC generation and data scrambling. Its highly integrated architecture allows for minimum external component count while still maintaining design flexibility.
