picoPower AVR® MCUs

Microchip AVR® microcontrollers are low-power, high-performance, and can handle demanding 8-bit applications. With a single cycle instruction RISC CPU, innovative picoPower® technology, and a rich feature set, the AVR architecture ensures fast code execution combined with the lowest possible power consumption. With picoPower technology, AVR MCUs feature true 1.8V supply voltage, minimized leakage current, sleeping BOD, ultra-low-power 32kHz crystal oscillator, digital input disable registers, clock gating, and flash sampling.
