Microchip ATSAM3U2C

ARM Cortex-M3, 96 MHz, 128 kB ROM, 32 kB RAM

The Microchip | SMART SAM3U is the industry’s first ARM Cortex M3 Flash microcontroller with on-chip high speed USB Device-and-Transceiver, SDIO/SDCard/MMC and SPI interfaces. This connectivity, together with the SAM3U’s 96 MHz/1.25 DMIPS/MHz operating frequency, makes the SAM3U the unique Cortex M3 device suited to applications with intensive communications requirements, such high speed gateways in industrial, medical, data processing and consumer applications. For rapid evaluation and code development, industry-leading third parties provide a full range of dev tools, RTOS, middleware and support services to reduce time-to-market to a minimum.
