Status: In Production
The SAM3S8C 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 512KB of flash memory and 64KB 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, two USARTs, two UARTs, two TWIs (I2C), three SPIs, I2S, PWM timer, six 16-bit timers, RTC, 16-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 collects data 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 3.6V and is available in 100-pin QFP and BGA packages.
