General Overview

Sophia Systems' own Sandgate 2 Development Board supports the Intel® PXA270 Applications Processor. This reference board enables you to develop the software at the same time as the hardware is being developed, greatly reducing your overall system development time. With the Intel® PXA270 Applications Processor installed, the Sandgate 2 reference design includes all the peripherals necessary for the development of Handheld devices and provides an excellent design base for your actual system.

The CD-ROM included with the board provides a board support package for Windows®CE 5.0 with Linux BSP solutions available upon request. A JTAG port can be used to download programs in FLASH memory or debug code via. a the serial port on the PC (JFLASH is included). Also the schematic, part list, CPLD code (source and binary) are all included so development and customization is not a problem.

For debugging code, there is both a JTAG port and Samtec connectors for in-circuit emulators. The combination of Sandgate II board and Sophia's EJ-Debug JTAG emulator provides on-chip debugging capability. And Sophia' UniSTAC™II for PXA270 (Full ICE) provides In-Circuit debugging.

I/O Ports

The PXA270 Sandgate Reference Design comes equipped with standard input and output ports. In addition to these, there is a expansion slot that easily extends the address and data bus so future devices can be added or developing products can be tested.

Local Area Network (LAN): Allows access to a network environment and supports NE2000. It meets CF I/F standards and the Ethernet driver is included.
Universal Serial Bus (USB): Three USB ports are built into the board: USB 2.0 (client), USB 1.1 (client), and USB 1.1 (host). The maximum transfer speed is 480Mbits/s. ActiveSync uses the USB to synchronize with a desktop PC, which allows for transferring data and programs to the development board.
IrDA port: Transfer data via infrared at a speed of 115.2Kb/s. It is a common way to exchange data with other PDA's or desktop PC, and convenient because it is wireless. ActiveSync supports IrDA.
Serial comm port: The most wildly used protocol for communicating with other devices. This can be used for Modems, Keyboards, Mouse, or printers.
Stereo Headphone Jack: Standard Jack used for head phones. PC speakers are also supported.
JTAG port: Used to download programs to system FLASH memory and for JTAG debuggers. A Cable is included that connects a desktop PC serial port. Software is also provided.

Audio Features:

• Integrated AC '97 Rev. 2.1 interface
• 20-bit stereo audio codec supporting programmable sample rates, and input/output gain control
• Stereo line input and mono microphone input
• Stereo line/headphone output with bass/treble control
• Headphone driver with short circuit protection and virtual ground for DC coupling

LCD Display: Toshiba color TFT-LCD

• 4" VGA display size for PDAs(personal digital assistants)
• Super high resolution (202 pixel per inch)
• 256k-colors
• Number of Pixels: 640(W) x 480(H)
• Backlight: Single CCFL, Sidelight type
• Pixel Pitch: 0.126(W) x 0.126(H) mm
• Dimensional Outline (typ.): 117.9(W) x 72.5(H) x 6.4(D) mm

Solution Sets

The power of the Sandgate 2 reference design is unleashed in combination with the complete debugging solutions available by Sophia Systems. From compilers and debuggers to JTAGs and Full In-Circuit Emulators (ICE). The solution sets provide all the tools needed to get your project developed, debugged and products out the door faster. For debugging code, there is a JTAG port and the combination of Sandgate 2G board and Sophia's EJ-Debug JTAG emulator for PXA270 provides on-chip debugging capability.
