ATSAM3S2C

The SAM3S2C is a member of the Microchip's 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 memory and 32KB of SRAM.

The extensive peripheral set includes a Full Speed USB device port with embedded transceiver, a high-speed 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 (I2C), three SPI, I2S, PWM timer, six 16-bit timers, RTC, 15-ch 12-bit ADC, 2-ch 12-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. DMA transfers the data to memory, 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.
