It operates over a wide range and is designed for applications including industrial automation, security, medical/diagnostic equipment, MIL/COTS, test and measurement, and transportation. WinSystems' design is based upon chipsets from Intel's long life embedded road map to ensure longevity of the core technology. WinSystems' applications engineers are available to provide technical support with initial board selection and free telephone assistance during the design-in and production phase of your project. Activity LEDs onboard for visual status Up to 300 second reset with watchdog timer +5 volt only operation Performance upgrade to WinSystems' EPX-C3 and EPX-GX500 RoHS compliant Quick Start Kits available for software development FUNCTIONAL CAPABILITY The EPX-855-G is a full-featured, high-performance single board computer with a variety of on-board peripherals which reduce the need for additional standard I/O peripheral cards. It is based on the Intel's popular 855GME chipset with the ICH4 communications controller and integrated Extreme Graphics 2 video 3D controller. The EPX-855-G features an Intel 1GHz Celeron®M-based ZC Dothan (ZCD) or 1.8GHz Pentium M processor. Both the CPU and system controller are supplied from Intel's Embedded Architecture Division for long-term availability. It supports a maximum of 1GB of industry-standard PC2700 SDRAM, Type I and Type II CompactFlash cards, plus support for IDE hard and 3.5" floppy disk drives.

The EPX-855-G offers a full set of I/O interfaces including one Gigabit 10/100/1000 Mbits/secs Ethernet port and one 10/100BaseT Ethernet port (with remote boot and WOL capability), analog VGA and dual channel LVDS flat panel video, a miniPCI connector that supports an optional 802.11 wireless networking module, four USB 2.0 ports, four serial COM ports, AC97 audio (5.1 codec), LPT and PS/2 ports for keyboard and mouse. Also onboard is a software programmable, 24-line digital I/O controller that provides input, output or output with readback for each I/O line. The board has PC/104 and PC/104-Plus...

WinSystems offers industrial-grade CompactFlash cards that provide operational SSD storage from -40° to +85°C for high capacity harsh embedded applications. They provide high sustained data transfer rates and an on-card wear leveling algorithm to extend the number of write cycles to the part. These RoHS-compliant cards will fit into any computer, SBC, instrument or camera with a CompactFlash socket, www.industrialcompactflash.com. supports the latest 2D and 3D APIs, delivering real-life environment and character effects. A 256-bit internal path enables up to four textures per pixel on a single...

Connectivity - The EPX-855-G has both onboard and PC/104 module population options for wired and wireless communications. One Gigabit 10/100/1000 Ethernet and one 10/100 Ethernet, four USB 2.0 ports, two RS-232/ 422/485 COM channels, and two RS-232 COM channels are standard on the board. Each port has overcurrent and in-rush protection provided by a National Semiconductor LM3526 power switch. Each device is a dual stage design including a thermal protection circuit. During a short-circuit/over-current event, the switch dissipating excessive heat is turned off, allowing the second switch to continue...

24-line parallel I/O - The EPX-855-G contains a highly versatile WS16C48 digital I/O controller. Each I/O line is individually programmable for input, output, or output with read-back operation. Each output channel is latched and has an open collector driver (with a pull-up resistor) capable of sinking 12mA of current. The major feature of this controller is its ability to monitor all 24 of the lines for both rising and falling digital edge transitions, and then interrupt the processor notifying it that a change-of-input status has occurred. Transition polarity is programmable and enabled on...

The board will operate without a battery since there is an EEPROM on board to store the CMOS set up data. However, current time and date information would not be maintained when the main +5V power is not present. PC/104 Expansion - The EPX-855-G has both a 16-bit PC/104 and a 32-bit PC/104-Plus interface and connector. PC/104 is electrically equivalent to the ISA bus and PC/104-Plus is the PCI bus for I/O functions requiring higher data transfer speeds. The EPX-855-G provides a common computer core from which engineers can add off-the-shelf or user-designed, application-specific PC/104 and PC/104-Plus...
