SMART SAM3S ARM® Cortex-M3 Microcontrollers


Based on the ARM® Cortex®-M3 core, the Atmel® SMART SAM3S Flash microcontroller (MCU) integrates features to simplify system design and reduce power consumption down to 2.3mW at 1MHz, 1.45mW/MHz at 64MHz operation and 1.6μA in backup mode with the Real-Time-Clock running. The series also includes parallel capture mode, and QTouch capacitive touch support.
