AT86RF233 2.4 GHz Transceiver

Microchip's AT86RF233 feature rich, low-power 2.4 GHz transceiver is designed for industrial and consumer IEEE 802.15.4, ZigBee, SP100, WirelessHART™, ISM, and high data rate applications. It is a true SPI-to-antenna solution providing a complete radio transceiver interface between the antenna and the microcontroller.

The device comprises an analog radio transceiver and 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 bi-directional differential antenna pins, used for transmission and reception, eliminate the need for an external antenna switch.

An internal 128 byte RAM buffers transmit and receive data. Two on-chip, low dropout (LDO) voltage regulators provide the internal analog and digital 1.8 V supply.
