The ATMEGA128RFA1-ZU is a 8-bit low-power CMOS Microcontroller based on the AVR enhanced RISC architecture combined with a high data rate transceiver for the 2.4GHz ISM band. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. The radio transceiver provides high data rates from 250kBps up to 2Mbps, frame handling, outstanding receiver sensitivity and high transmit output power enabling a very robust wireless communication.
