AT86RF212, AT86RF231, & AT86RF233 RF Transceivers

AT86RF212, AT86RF231, and AT86RF233 RF Transceivers are SPI-to-antenna solutions, designed to provide a complete radio transceiver interface between the antenna and the microcontroller. These devices comprise the analog radio transceiver and the digital demodulation including time and frequency synchronization, and data buffering. All RF-critical components are integrated on a single chip minimizing the number of required external components to the antenna, crystal, and decoupling capacitors. The bidirectional differential antenna pins, used for transmission and reception, eliminate the need for an external antenna switch.
