ATmega1284P 8-bit Microcontrollers

Atmel / Microchip ATmega1284P is a high-performance 8-bit AVR^® RISC-based microcontroller that executes powerful instructions in a single clock cycle. Throughputs close to 1MIPS per MHz are achieved in a single clock cycle, giving the designer the benefit of optimizing the device for power consumption versus processing speed.
