General Description
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 kbps. 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.
