ATSAM3U ARM-CM3开发板

The ATSAM3U ARM-CM3 Board is an ARM embedded evaluation board produced by Embest, integrate the ATMEL Cortex-M3 core-based processor ATSAM3U4E, operating at 96 MHz frequency. The board features USB, I2C, MCI interface, TFT-LCD, USART interface, 96 I/O port, EBI support SRAM/NOR/NAND memory, etc. Plenty of software examples, which can be used in Keil MDK environment, are accompanied in CDROM. You can use the Cortex-M3 based AT91SAM3U Evaluation Board to generate and test application programs for the ATMEL SAM3U Series microcontroller family. With this hands-on process, you can determine the hardware and software requirements for current and future product development.

The AT91SAM3U Evaluation Board ships with the AT91SAM3U device that is a superset of several other device variants of the ATMEL SAM3U microcontroller series. The AT91SAM3U Board contains all the hardware components required in a single-chip AT91SAM3U4E system.
