ATSAM3S1C

The SAM3S1C 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 64KB of flash memory and 16KB 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 with 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 QTouch library offers 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.

The device operates from 1.62V to 3.6, is available in 100-pin QFP and QFN packages, and is pin-to-pin compatible with the SAM3N1C.
