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 bidirectional communications affordable for applica-tions such as secured transmissions with hand-shake procedures, new features and services, etc. The AT86RF 211 can easily be configured to provide the optimal solution for the user's application: choice of external filters vs. technical requirements (bandwidth, selectivity, immunity, range, etc), and software protocol (single channel, mul-tiple 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 microcontroller only when a valid inquiry is detected.
