MRF89XA
All critical RF and baseband functions are integrated in
the MRF89XA, which minimizes the external
component count and reducing design time. The RF
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 required 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) and United States (FCC Part
15.247 and 15.249) regulatory standards.
