Description

The SAM3S series are 18 Cortex-M3-based Flash MCUs that integrate features to simplify PCB design and reduce power consumption down to 2.3 mW at 1 MHz operation. At maximum operating frequency of 64MHz the device consumes 1.45mW/MHz. They provide processing power and features such as system control, sensor interfaces, 64k to 256kByte Flash memory options, an optional external parallel bus interface, connectivity capabilities and user interface support. Additional features include On-Die Termination (ODT), USB Device, SDIO, Parallel PIO signal capture, 12-bit ADC and DAC, 4 UARTs, dual I2C, I2S, timers, unique chip ID, and power and reset management. The SAM3S’s supply voltage ranges from 1.62 to 3.6V operation and package options from 48-pin QFP and QFN up to 100-pin QFP and BGA. Inspired by the best-selling SAM7S series, the SAM3S provides the ideal migration path to a more powerful and feature-rich MCU, while preserving hardware and software investments.
