The Atmel AT86RF233-ZU is a feature rich, extremely low-power 2.4GHz radio transceiver designed for industrial and consumer ZigBee/IEEE 802.15.4, RF4CE, 6LoWPAN, and high data rate 2.4GHz ISM band applications. The AT86RF233-ZU is a true SPI-to-antenna solution. All RF-critical components except the antenna, crystal, and de-coupling capacitors are integrated on-chip. MAC and AES hardware accelerators improve overall system power efficiency and timing.
