The Atmel AT86RF232 is a low-power 2.4GHz radio transceiver designed for consumer ZigBee/IEEE 802.15.4, RF4CE, 6LoWPAN, and 2.4GHz ISM band applications. The radio transceiver is a true SPI-to-antenna solution. All RF-critical components except the antenna, crystal and de-coupling capacitors are integrated on-chip. Therefore, the AT86RF232 is particularly suitable for applications like:

 2.4GHz IEEE 802.15.4 and ZigBee systems

 RF4CE systems

 6LoWPAN systems

 Wireless sensor networks

 Residential and commercial automation

 Health care

 Consumer electronics

 PC peripherals

The AT86RF232 can be operated by using an external microcontroller like Atmel AVR® microcontrollers.
