General Description
The MRF89XA is a single chip FSK/OOK trans-
ceiver 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 whitening.
Its highly integrated architecture allows for minimum
external component count while still 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 Part 15.247 and 15.249)
regulatory standards.
