The ATmega128RFA1 is a low-power CMOS 8 bit microcontroller based on the AVR
enhanced RISC architecture combined with a high data rate transceiver for the 2.4 GHz
ISM band. It is derived from the ATmega1281 microcontroller and the AT86RF231 radio
transceiver.
By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
The radio transceiver provides high data rates from 250 kb/s up to 2 Mb/s, frame handling, outstanding receiver sensitivity and high transmit output power enabling a very robust wireless communication.
