The Atmel® SAM3S8B is a member of the Atmel SAM3S series microcontrollers based on the high-performance 32-bit ARM® Cortex™-M3 RISC processor. It operates at a maximum speed of 64MHz and features 512KB of Flash and 64KB of SRAM. The extensive peripheral set includes a FS USB device port with embedded transceiver, a HS multimedia card interface for SDIO/SD/MMC, two USARTs, two UARTs, two TWIs, three SPIs, I2S, PWM timer, six 16-bit timers, RTC, 12-bit ADC/DAC and an analog comparator. The Atmel QTouch® Library offers an easy way to implement buttons, sliders and wheels. The parallel data capture mode on the PIOs collects data from external devices not compliant with standard memory read protocols, such as low-cost image sensors. The data is then transferred to memory by DMA offloading the CPU. The device operates from 1.62V to 3.6V and is available in 64-pin QFP and QFN packages.
