Microchip ATSAM3S2B

ARM Cortex-M3, 64 MHz, 128 kB ROM, 32 kB RAM

The Microchip | SMART SAM3S Cortex M3 Flash MCU integrates features to simplify system design and reduce power consumption down to 2.3 mW at 1 MHz, 1.45mW/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.
