A PC/104-compatible 1 GHz single board computer (SBC) is designed for headless space- and power-limited systems in medical, communications, security, transportation, utilities, Mil/COTS and industrial test/measurement applications. The PCM-VDX-2-512 from WinSystems has two Ethernet, four USB 2.0 and four asynchronous serial channels plus expansion connectors for both PC/104 and Mini PCI I/O cards. The board measures 90 mm x 96 mm (3.6” x 3.8”), draws 5.5W, and will operate from -40° to +85°C without a fan. The PCM-VDX-2-512 is based on the DM&P ultra-low-power Vortex86DX processor and is populated with 512 Mbyte of soldered-on DDR2 SRAM plus a 1 Mbyte SRAM that can be battery backed. Its x86 architecture runs Linux, DOS and other x86-compatible operating systems as well. This SBC is supplied with downloadable drivers that are available free of charge from WinSystems’ website.

Electrostatic Discharge (ESD) suppressors rated to ±15kV are included on the USB, Ethernet and serial data ports for additional protection and will withstand multiple ESD strikes.  Additionally, the USB ports have in-rush and over-current protection. All four independent, full-duplex serial channels support RS-232/422/485 levels and operate at data rates up to 115.2 Kbit/s. The PCM-VDX-2-512 also has a PATA controller that will support a Compact Flash card and an IDE drive. Other onboard peripherals include 16 lines of TTL-compatible digital I/O, PS/2 keyboard and mouse controllers, LPT interface, real-time clock, watchdog timer, activity LEDs, and a piezo speaker for audio annunciation of the BIOS status beep codes.  

Mini PCI and PC/104 connectors support expansion I/O cards for wireless networks, video, etc.  With this diverse range of functions, many applications will not require any additional I/O cards.

WinSystems can customize this SBC for OEM applications either by depopulating certain features or by adding soldered-on flash memory, a CF card retention clip, and/or a Mini PCI video card. The processor speed and amount of SDRAM can be reduced to lower the price and power consumption as well. The PCM-VDX-2G-512 is priced at $342 in OEM quantities.
