The AT86RF230 is a 2.4 GHz radio transceiver from Atmel. It is specially designed for
IEEE 802.15.4 and ZigBee applications. Main features are:
• Low power consumption.
• Large link budget (104 dBm).
• True 1.8 volts operation.
• Minimized number of external components needed.
The only required external components are antenna, 16 MHz crystal and four
decoupling capacitors. An easy-to-use Serial Peripheral Interface (SPI) is defined for
accessing the radio’s register file. Please consult the AT86RF230 radio transceiver’s
datasheet for further information about its specifications, operating modes, registers
etc.
The antenna output of the AT86RF230 is differential. This configuration is beneficial
because:
• Immunity to electromagnetic interference.
• Immunity to power-supply noise.
• Immunity to ground noise.
• Suppression of even-order harmonic.
