MCU features Cortex-M3 core, 480-Mbit/s USB, 256 Kbytes of flash
The SAM3U flash 32-bit MCU is based on a ARM Cortex-M3 core with a 96MHz clock rate at 1.8 V and features a high-speed 480-Mbit/s USB device. It also has a 336-Mbit/s SDIO/SD/MMC interface, a 42-Mbit/s SPI port, a 1-Msample/s 12-bit A/D converter, and a 500+-Mbit/s external bus interface. The chip provides a five-layer bus matrix, 23 DMA channels, up to 56 Kbytes of SRAM split in three blocks, and up to 256 Kbytes of flash in two banks. The dual-bank flash supports in-application programming.
Additional features include five UARTs, dual I2 C, I2 S, timers, and a chip ID. The device operates at 1.62 to 3.6 V, and comes in 100- and 144-pin QFP and BGA packages. The chip’s high-speed DMAs have a dedicated layer in the bus matrix, maximizing parallel data transfers. The high data bandwidth architecture enables the IC to simultaneously stream several 100-Mbit/s peripherals, while processing the payload, and controlling the system.
