SAM3U Arm® Cortex®-M3 Flash-Based Microcontrollers

Microchip Technology SAM3U Arm® Cortex®-M3 Flash-Based Microcontrollers are Arm Cortex-M3 Flash Microcontrollers with on-chip high-speed USB Device-and-Transceiver, SDIO/SDCard/MMC, and SPI interfaces. This connectivity, together with the SAM3U's 96MHz/ 1.25 DMIPS/MHz operating frequency, makes the SAM3U the unique Cortex M3 device suited to applications with intensive communications requirements, such as 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 development tools, RTOS, middleware, and support services to reduce time-to-market to a minimum.
