Description

Atmel’s SAM3U is the industry’s first Cortex-M3 Flash microcontroller with an on-chip high-speed USB Device (including transceiver) at 480 Mbps. In addition to USB, the SAM3U products come with multiple communication interfaces such as USART, SPI and I2C, as well as an external memory conHtroller, SDIO/SD/MMC controller, ADCs and timers. 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. The SAM3U is supported by a rapidly growing number of development tools, real-time operating systems (RTOS), middleware products and technical support services. Atmel provides a software package with register descriptions and device drivers for all peripherals, along with project examples that ease the use of the microcontroller. The SAM3U Evaluation Kit (ATSAM3U-EK) is available for benchmarking and a quick start in application development. It includes a colour touch screen TFT display, high speed USB device connection, SD card, audio and debug interfaces.
