Description

General part information

ATSAM3X4C Series

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.
