ATSAM3S2BA-AU Product Details


The SAM3S2B 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 128KB of flash and 32KB 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 SPI, I2S, PWM timer, three 16-bit timers, RTC, 10x12-bit ADC, 2x12-bit DAC and an analog comparator. The SAM3S2B is ready for capacitive touch thanks to the QTouch® library, offering an easy way to implement buttons, wheels and sliders. 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. It operates from 1.62V to 3.6V and is available in 64-pin QFP and QFN packages. The SAM3S2B is pin-to-pin compatible with the SAM3N2B and SAM7S64.
