SAM3S Series Microcontroller Units


The SAM3S series from Atmel simplifies system design and reduces power consumption


The Atmel SAM3S Cortex™ M3 Flash MCU integrates features to simplify system design and reduce power consumption down to 2.3 mW at 1 MHz, 1.45 mW/MHz at 64 MHz operation and 1.6 uA 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. Datasheet Atmel's SAM3S Series MCUs
Features

  • Simplified System Design and Low System Cost
    Integrated serial resistors eliminate the need for external resistors to preserve signal integrity, resulting in reduced BOM cost, real estate savings, and simplified system design.
  • Parallel Capture Mode
    The SAM3S is the first ARM® MCU with parallel data capture mode on PIOs and DMA support. The parallel data capture mode on the PIOs complements the external bus interface for data collection from external devices that are not compliant with standard memory read protocols, such as low-cost image sensors.
  • Atmel QTouch Capacitive Touch Support
    The SAM3S series is touch-ready, offering native support for Atmel QTouch® technology for easy implementation of buttons, sliders, and wheels in your application.
  • Safety and Security
    Memory protection unit improves code protection and secures multi-application/task execution. Unique 128-bit ID and scrambled external bus interface ensure software confidentiality while the hardware CRC checks memory integrity.
