SAM3S General-purpose Flash Microcontrollers by Atmel

Semiconductor Vendor with ARM Processor RTL license from ARM

Product Description

The Atmel® SAM3S is a highly-integrated, energy-efficient Cortex™-M3 microcontroller, featuring up to 1MB of Flash and 128KB of SRAM. The extensive peripheral set includes a FS USB device port with embedded transceiver, USART, two UARTs, two TWIs, two SPIs, I2S, PWM timer, three 16-bit timers, RTC, eight 12-bit ADCs and an analog comparator. Power consumption levels are 2.3 mW at 1 MHz, 1.45mW/MHz at 64 MHz operation and 1.6 uA in backup mode with the RTC running.
The Atmel SAM3S family offers native support for Atmel QTouch® capacitive touch technology. This ‘touch-ready’ design simplifies the implementation of touch-based functionality including buttons, sliders and wheels.
The Atmel 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.
The devices operate from 1.62V to 3.6V and are available in 48-, 64- and 100-pin QFP/QFN/BGA packages.
