Microchip Technology Microcontroller
The Microchip technology SAML1 family type, TQFP package, surface mount, 48-pin ARMCortex-M0 based 32-bit microcontroller has a maximum voltage rating of 3.63V. It is an ultra-low-power ATSAML1 based flash microcontroller (MCU) that features power management technologies and consumes under 35MHz in active mode and 200nA in sleep mode. In addition to ultra-low-power performance, this device features full-speed USB host and device, event system and sleepwalking, 12-bit analogue, AES, capacitive touch sensing and built-in op-amps.
