SAM3S ARM® Cortex®-M3 Flash-Based Microcontrollers

Microchip Technology SAM3S ARM® Cortex®-M3 Flash-Based Microcontrollers family integrates features to simplify system design and reduce power consumption down to 2.3mW at 1MHz, 1.45mW/MHz at 64MHz operation, and 1.6uA in backup mode with the RTC running. Inspired by the best-selling SAM7S series, the SAM3S is the ideal migration path to a more powerful and feature-rich MCU. A renewed peripheral set provides system control, sensor interfaces, an optional external parallel bus interface, connectivity, and user interface support.
