Description
The AT86RF211 (aka: TRX01) is a single chip transceiver dedicated to low power
wireless applications, optimized for licence-free ISM band operations from 400 MHz to
950 MHz. Its flexibility and unique level of integration make it a natural choice for any
system related to telemetry, remote controls, alarms, radio modems, Automatic Meter
Reading, hand held terminals, high-tech toys, etc. The AT86RF211 makes bidirec-
tional communications affordable for applications such as secured transmissions with
hand-shake procedures, new features and services, etc. The AT86RF211 can easily
be configured to provide the optimal solution for the user’s application: choice of exter-
nal filters vs. technical requirements (bandwidth, selectivity, immunity, range, etc), and
software protocol (single channel, multiple channel, FHSS). The AT86RF211 is also
well adapted to battery operated systems, as it can be powered with only 2.4V. It also
offers a “Wake Up” receiver feature to save power by alerting the associated micro-
controller only when a valid inquiry is detected.
