A member of the Microchip's SAM4L family of Flash microcontrollers based on the ARM® Cortex®-M4 processor, the ATSAM4LS8C delivers the lowest power in active mode (90uA/MHz) as well as sleep mode (1.5uA) and the shortest wake-up time (down to 1.5us) in a Cortex-M4 device. Along with 512KB of embedded Flash, the device features a USB device, peripheral event system and SleepWalking intelligent peripherals. Integrated Microchip QTouch technology makes it easy to bring capacitive touch functionality to your hardware.
