This module is an overview of the SAM3U and the different versions available. The SAM3U is the first Cortex®-M3 MCU with USB High Speed Device and integrated transceiver capable of running at up to 96 MHz. General-purpose DMA and distributed SRAM are embedded to sustain high data transfer rates between multiple high-speed peripherals such as the High-speed SDIO, SD/MMC Card, SPI snd 12-bit ADC. The Cortex-M3 core improves code protection and secures multi-application/ task execution. It is also the first Cortex-M3 MCU with the boot flash bank selection for IAP.
