• More About Atmel

The Atmel ATmega128RFA1 wireless AVR ® microcontroller ( MCU ) is an IEEE 802.15.4 compliant single-chip that combines the industry-leading AVR MCU and best-in-class 2.4 GHz RF transceiver to provide the industry's highest RF performance for single-chip devices with a link budget of 103.4dBm. The Atmel ATmega128RFA1 wireless AVR MCU features Wake-on Radio, 32-bit MAC symbol counter, temperature sensor, automatic transmission modes, 128-bit AES crypto engine, true random number generator, high data rate modes, and antenna diversity support. The Atmel ATmega128RFA1 MCU executes powerful instructions in a single clock cycle, allowing the device to achieve throughputs approaching 1 MIPS per MHz of clock cycle for optimized power consumption versus processing speed. The radio transceiver on the ATmega128RFA1 provides high data rates from 250 kb/s up to 2 Mb/s, frame handling, outstanding receiver sensitivity, and high transmit output power.
