picoPower® Microcontrollers

Microchip picoPower® 8- and 32-bit low, high-performance Microcontrollers (MCUs) meet the tough requirements for portable and battery-operated applications. Microchip picoPower technology is found in the tinyAVR®, megaAVR®, AVR®, XMEGA™, and AVR UC3 MCUs. Microchip picoPower technology enables AVR MCUs to operate at the industry's lowest power consumption with 650 nA with an RTC running and 100 nA in Power Down sleep.
