Description
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 16bit 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.
