The Intel PXA255 processor is using Intel XScale technology and designed for advanced devices that run the most impactful mobile applications. A pin-for-pin compatible, drop-in replacement for the processor, it is a highly integrated, 32-bit RISC processor that combines the efficiency of Intel design with the ARM v.5TE instruction set architecture can work up to 400MHz. The Intel PXA255 processor peripheral control module offers 16 channel configurable DMA controller, integrated LCD controller with unique DMA for fast color screen support, Bluetooth, serial ports including IrDA, IIS, IIC, AC97, three UARTs, SPI
and enhanced SSP, USB end point interface, and MMC/SD Card support for expandable memory and I/O functionality. It delivers industry leading processing power with built-in multimedia capabilities for high performance and hand-held functionality and designed to optimize low power consumption and high performance processing for a wide range of wireless and networking applications and rich services.

Embest PXA255DB Evaluation Board is intended as a low cost evaluation platform for Intel XScale PXA255 device. The board expands all features of Intel XScale PXA255 processor and supports various additional interfaces including FFUART, BTUART, IrDA UART, SD/MMC/SDIO, CF, UART for TTL, LCD, power, USB, Ethernet, JTAG, Bus expansion, etc. The board has a flexible design using a CPU board and an expansion board. This is convenient for users to update and upgrade their boards and effectively protects customers' prophase resources. Users can fully take use of the board to meet your development requirements and applications.
