SAM4L ARM Cortex-M4 Microcontrollers

Microchip SAM4L ARM Cortex-M4 Microcontrollers (MCUs) deliver the lowest power in active mode (down to 0.9µA/MHz) and sleep mode with full RAM retention (1.5µA) with the shortest wake-up time (down to 1.5µs). Microchip SAM4L ARM Cortex-M4 Microcontrollers offer picoPower® technology, highly efficient signal processing, ease of use, and high-speed communication peripherals. SAM4L ARM Cortex-M4 MCUs are ideal for power-sensitive designs in the industrial, healthcare, and consumer application areas.
