• Manufacturer Part Number: mrf89xa
• Description: Ultra-low Power, Integrated Ism Band Sub-ghz Transceiver
• Manufacturer: Microchip Technology Inc.

MRF89XA
All critical RF and baseband functions are integrated in
the MRF89XA, minimizing the external component
count
communication parameters are made programmable
and most of them may be dynamically set. A
microcontroller, RF SAW filter, 12.8 MHz crystal, and a
few passive components are all that are needed to
create a complete, reliable radio function. The
MRF89XA uses several low-power mechanisms to
reduce overall current consumption and extend battery
life. Its small size and low power consumption makes
the MRF89XA ideal for a wide variety of short range
radio applications. The MRF89XA complies with
European (ETSI EN 300-220 V2.3.1) and United States
(FCC Part 15.247 and 15.249) regulatory standards.
