-40° to +85° C PC/104 SBC with Dual Ethernet

Compatible Operating Systems: Linux and other x86-compatible RTOSes
Supported Architectures: PC/104, Vortex86DX processor, miniPCI

The PCM-VDX-2 is a highly integrated, PC/104 single board computer (SBC) designed for space-limited and low-power applications. It is a full-featured SBC that includes a 1 GHz Vortex86DX CPU with 512KB of DRAM. I/O support includes two 10/100 Ethernet ports, four USB 2.0 ports with overcurrent protection on each channel, and four COM channels. The PCM-VDX-2 includes the standard PC controllers for IDE hard disks, CompactFlash devices, PS/2 mouse and keyboard controller, LPT and PC/104 expansion connectors all on a single 90mm x 96mm module.

There are 16 bits of TTL-compatible digital I/O with each line individually programmable for input, output, or output with read-back operation. The major feature of the onboard digital I/O controller is its ability to monitor the 16 lines for either rising or falling digital edge transitions, latch them, and then interrupt the host processor notifying it that a change-of-input status has occurred.

There is also a depopulated version of this SBC called the PCM-VDX-1 that is designed to replace legacy 386, 486, and early generation PC/104-compatible Pentium SBCs.

The PCM-VDX has x86 PC software compatibility which assures a wide range of tools to aid in the designer’s application program development and checkout. It supports both the Linux operating system and other real time operating systems.

Its low power dissipation permits fanless operation over a temperature range from -40° to +85°C. This board is well suited for rugged applications requiring excellent processor performance in an embedded PC design.
