ATSAM3X4EA-AU Microcontroller, Cortex M3, 84MHz, 256KB Flash,64KB RAM,LQFP-144

Based on the ARM® Cortex®-M3 processor, the Microchip's SAM3X4E runs at 84MHz and features 256KB of flash memory in 2 x 128KB banks and 68KB of SRAM in 2 x 32KB banks, with an additional 4KB as NFC (NAND Flash controller) SRAM.

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 SAM3X4E 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 Microchip QTouch Library is available for the SAM3X4E for easy implementation of buttons, sliders and wheels.
