ATMEGA256RFR2-ZU (MICROCHIP)

The ATMEGA256RFR2-ZU is a 8-bit low-power CMOS Microcontroller Unit 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 designed to optimize power consumption versus processing speed. The radio transceiver provides high data rates from 250kb/s up to 2Mb/s, frame handling, outstanding receiver sensitivity and high transmit output power enabling a very robust wireless communication. The power-down mode saves the register contents but freezes the oscillator, disabling all other chip functions until the next interrupt or hardware reset. In power-save mode, the asynchronous timer continues to run, allowing the user to maintain a timer base while the rest of the device is sleeping.
