The ATSAM3X8CA-AU is a SMART SAM3X series 32-bit Flash Microcontroller based on the high-performance ARM Cortex-M3 RISC processor. It operates at a maximum speed of 84MHz and features 512kB of flash memory in 2 x 256kB banks and 96kB of SRAM in 64kB +32kB banks. Its highly-integrated peripheral set includes Ethernet, dual CAN, High Speed USB MiniHost and device with on-chip PHY, high-speed SD/SDIO/MMC and multiple USARTs, SPIs, TWIs (I2C) and one I2S. The SAM3X8C also features a 12-bit ADC/DAC, temperature sensor, 32-bit timers, PWM timer and RTC. The 16-bit external bus interface supports SRAM, PSRAM, NOR and NAND flash with error code correction. The Atmel QTouch? Library is available for the SAM3X8C for easy implementation of buttons, sliders and wheels. The device operates from 1.62 to 3.6V.
