Atmel’s SAM3U series is a member of a family of Flash microcontrollers based on the high performance 32-bit ARM Cortex-M3 RISC processor. It operates at a maximum speed of 96 MHz and features up to 256 Kbytes of Flash and up to 48 Kbytes of SRAM. The peripheral set includes a High Speed USB Device port with embedded transceiver, a High Speed MCI for SDIO/SD/MMC, an External Bus Interface with NAND Flash controller, 4x USARTs, 2x TWIs, 1x SPI, as well as 1 PWM timer, 3x general purpose 16-bit timers, an RTC, a 12-bit ADC and a 10- bit ADC.

The SAM3U architecture is specifically designed to sustain high speed data transfers. It includes a multi-layer bus matrix as well as multiple SRAM banks, PDC and DMA channels that enable it to run tasks in parallel and maximize data throughput.It can operate from 1.62V to 3.6V and comes in 100-pin and 144-pin LQFP and BGA packages. The SAM3U device is particularly well suited for USB applications: data loggers, PC peripherals and any high speed bridge (USB to SDIO, USB to SPI, USB to External Bus Interface).
