Industry’s First Cortex M3 MCU with On-chip High-speed USB
The Atmel® 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.
Key Features
High-Speed USB — The SAM3U is the first Cortex M3 microcontroller with high-speed USB and an integrated transceiver for fast up/downloading of data, robust EMI tolerance, and plug-and-play high-speed serial interconnectivity.
Atmel QTouch Capacitive Touch Support — The SAM3U is touch-ready, offering native support for Atmel QTouch® technology for easy implementation of buttons, sliders and wheels in your application.
High Performance — Features a 96 MHz maximum operating frequency and a high data-bandwidth architecture based on a 5-layer bus matrix with 22 DMA channels and distributed memory.
Dual-Bank Flash — Provides safe in-application programming (IAP) including the boot program
Memory Protection Unit — Improves code protection and secures multi-application/task execution.
