More information

The VIPER board offers a long list of features making it ideal for power sensitive embedded communications and multimedia applications. The board has been designed to take advantage of the power saving modes of the PXA255 processor and other onboard peripherals to achieve an incredible 1.9W maximum power consumption. The VIPER also supports a very low power standby mode of just 250mW.

The VIPER board includes a TFT/STN flat panel graphics controller, onboard soldered SDRAM and resident Flash, 10/100baseTx Ethernet, 5 serial ports, I²C controller, dual USB host controller, USB client, AC97 audio/codec, CompactFlash interface (CF+), and a standard PC104 bus expansion connector. The PC104 format is an industrial form factor measuring 96mm x 91mm.

The VIPER is supported with low cost Entry Level Development Kit for embedded Linux and also system level Development Kits for Windows CE 5.0, embedded Linux, VxWorks 5.5 and QNX Neutrino. The system level Kits include a full metal enclosure (VIPER ICE) fitted with the VIPER-UPS and an optional quarter VGA colour touch-screen display. To speed up the process of system integration, you can purchase individual cables and the Ethernet adapter module used within the VIPER ICE enclosure and the associated Development Kits. The VIPER board can be connected directly to the VIPER-I/O module to provide opto-isolated inputs, outputs, relay control, push switches and status LEDs.

For cost sensitive high volume applications Arcom offers the VIPER-Lite - an alternative configuration based on the 200MHz PXA255 fitted with 64Mbytes DRAM and 16Mbytes Flash. Check out the VIPER-Lite web page for more details.

One of the practical issues to be resolved by OEM users is the connection of displays from different manufacturers. Arcom has made this easy by offering a number of display interface adapters to create direct connection to a wide range of displays from companies such as NEC, Sharp, Optrex, Hitachi and Kyocera. Arcom also provides a low cost module for converting the output signalling to LVDS - a system for driving displays located up to 5m from the video source. A complementary adapter is also available to convert from LVDS back to parallel digital. This adapter is particularly useful for small form factor displays which do not support LVDS input.

Video display interface options (using Arcom Flat Panel InterFace modules)
VIPER-FPIF1	FPIF-CRT	FPIF-LVDS-Tx	FPIF-LVDS-Rx

Allows easy connection between the VIPER flat panel output connector and most parallel digital flat panel displays.	Converts the VIPER flat panel output to a standard analogue RGB VGA signal for use with a regular monitor.	Converts the VIPER flat panel output to a standard LVDS MDR connector or Hirose connector for remote displays (up to 5m from the VIPER).	Converts the LVDS signals back to parallel digital data to drive a parallel digital flat panel display.
