Overview:

The Embest SBC6845 is a high-performance ARM embedded Single Board Computer (SBC) based on Atmel's AT91SAM9G45AT91SAM9G45 processor. It is a compact board with frequently used functions. It is designed for a wide range of applications including Industrial Control Terminal, Intelligent Instrumentation, Data Acquisition and Analysis, Medical products, and Network Terminals.

The Atmel SAM9G45 is a 400MHz ARM926 based embedded microprocessor with DDR2 and LPDDR. The board supports a wide range of connectivity and user interface peripherals, as well as a dual external bus interface. The SBC6845 extends many hardware interfaces including serial ports, USB Hosts, CAN, RS485, Ethernet, SD card, Audio out, keypad, LCD, and Touch screen. The SBC6845 also have 128MBytes DDR2 SDRAM, 256MBytes NAND Flash and 4MBytes Data Flash on board memory.

Embest also offers opptional 4.3 inch and 7 inch Touch Screen LCDs, user can connect these LCD/TSP through 2.54mm pitch 2*20-pin on board connector, with the provided LCD drivers users are ready to use this as an out of box solution. If user wants to use large size LCD with the SBC6845 board, Embest also offers one RGB-to-LVDS converter board SBC6000_LVDS as an option which can convert the LCD RGB signal to LVDS signal to create the large size LCD connection possibility.

The SBC6845 Single board computer is ready to run Linux 2.6.30 open source operating system and WinCE 6.0 operating system. Linux source code, WinCE BSP, User Manuals and development tools are also included to help the user with their own development. The board is an ideal platform for evaluation and early development work. The board also has a compact and logic layout and user can use it directly for their next embedded design which can help to shorten the time from embedded board to product release.
