AT86RF211DAI-R

AT86RF211DAI-R Datasheet

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 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 external 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 microcontroller only when a valid inquiry is detected.

All these operations are carried out via a three-wire serial interface. The chip is set-up by the microcontroller frequency and mode Rx or Tx . Then it acts like a "pipe" any data entering DATAMSG is immediately radiated Tx or any wanted signal collected by the aerial is demodulated, transferred to the microcontroller by the same pin DATAMSG Rx as reshaped bits. No data is stored or processed into the chip. See Figure Note In Rx mode, a clock recovery DATACLK is available on the digital interface to provide the microcontroller with a synchronization signal. The chip is set up in a special Rx mode called sleep mode. The chip wakes up periodically thanks to its internal timer stand alone procedure, the microcontroller is in powerdown mode , waiting for an expected message previously defined. If no correct sequence is received, the periodic scan continues. If a correct message is detected, its data field is stored into the AT86RF211 up to 32 bits and an interrupt is generated on the WAKEUP pin.

Then it acts like a "pipe" any data entering DATAMSG is immediately radiated Tx or any wanted signal collected by the aerial is demodulated, transferred to the microcontroller by the same pin DATAMSG Rx as reshaped bits. No data is stored or processed into the chip. See Figure Note In Rx mode, a clock recovery DATACLK is available on the digital interface to provide the

The chip is set up in a special Rx mode called sleep mode. The chip wakes up periodically thanks to its internal timer stand alone procedure, the microcontroller is in powerdown mode , waiting for an expected message previously defined. If no correct sequence is received, the periodic scan continues.

If a correct message is detected, its data field is stored into the AT86RF211 up to 32 bits and an interrupt is generated on the WAKEUP pin.
