The SAM3S2C 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, an external bus interface featuring a Static Memory Controller providing connection to SRAM, PSRAM, NOR Flash, LCD module and NAND flash, two USARTs, two UARTs, two TWIs, three SPI, I2S, PWM timer, six 16-bit timers, RTC, 1six 12-bit ADC, 2x12-bit DAC and an analog comparator. The SAM3S2C 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 complements the external bus interface for data collection from external devices not compliant with standard memory read protocols, such as low-cost image sensors. Data is transferred to memory by DMA offloading the CPU. It operates from 1.62V to 3.6V and is available in 100-pin QFP and QFN packages. The SAM3S2C is pin-to-pin compatible with the SAM3N2C.
