A member of the Atmel® SAM3U family of flash microcontrollers based on the high-performance 32-bit ARM® Cortex™-M3 RISC processor. It operates at a maximum speed of 96MHz and features 64KB of flash and 20KB of SRAM. The peripheral set includes a HS USB device and Phy at 480Mbps, HS multimedia card interface for SDIO/SD/MMC, a 16-bit external bus interface supporting NAND flash, four USARTs, two TWIs, 5x SPIs, I2S, four PWM timers, three 16-bit timers, RTC, 8x12-bit and 8x10-bit ADC. The architecture is designed to sustain high-speed data transfers. The multi-layer bus matrix, multiple SRAM banks, PDC, and DMA support parallel tasks and maximize data throughput. The SAM3U1E operates from 1.62V to 3.6V and is available in 144-pin LQFP and BGA packages.
