Embest ATEB9200 Evaluation Board

Atmel's AT91RM9200 SoC (System-on-chip) is built around the 200 MIPS ARM920T ARM Thumb processor with integrated 16K-byte instruction and 16K-byte data cache memories. It incorporates a rich set of system and application peripherals and standard interfaces in order to provide a single-chip solution for a wide range of applications that require maximum functionality at minimum power consumption at lowest cost. It features an ETM (Embedded Trace Macrocell) and an enhanced ARM architecture 4v MMU and supports various memories including SDRAM, Static Memory, Burst Flash, CompactFlash, SmartMedia and NAND Flash integrated with a wide range of standard interfaces containing serial interfaces, Ethernet MAC interface, USB2.0 Full Speed Host and Device ports, I2S, I2C, SPI, etc. To complete the offer this SoC benefits from many debug features including JTAG-ICE, a dedicate UART debug channel (DBGU) and an embedded run-time trace.



Embest ATEB9200™ Evaluation Board is based on Atmel's AT91RM9200 ARM9 microcontroller running at 180MHz. The board itself is provided with plenty of example programs. It is a complete Linux development environment that includes all the necessary hardware and software to allow embedded engineers to achieve fast result and reap the benefit of the open source software. Due to the extensive on-chip functions, CPU-intensive applications requiring low power consumption can be realized at low cost. Typical applications are POS (Point-of sale), medical system and industrial automation requiring Ethernet and USB. Users can fully take use of it for evaluation, development and applications.
