Low Power PC/104 Module with Vortex86DX Processor

The Tomcat single board computer from VersaLogic is based on the ultra-low power DMP Vortex86DX processor and supports PCI and ISA stackable expansion boards.

With no moving parts (fanless operation), full industrial temperature rating, soldered-on RAM, and a compact rugged form factor the Tomcat is ideal for operation in harsh, mobile, and/or remote environments.

The Tomcat is “headless” and has been designed for applications that do not require any type of video output.


Tomcat’s standard on-board features include Fast Ethernet, up to 512 MB soldered-on DDR2 RAM, two USB 2.0 ports, four serial ports, IDE and LPT interfaces, a CompactFlash socket for removable flash storage, and two general purpose timers.

The PC/104-Plus platform provides plug-in access to industry standard expansion modules. Support for keyboard and mouse is provided via USB or PS/2.

Available in both commercial (0° to +70°C) and industrial (-40° to +85°C) temperature versions; the Tomcat provides fanless operation and meets MIL-STD-202G specifications for shock and vibration.

Transient voltage suppression (TVS) devices on critical I/O ports provide enhanced electrostatic discharge (ESD) protection for the system.

The Tomcat is compatible with a variety of x86 operating systems including Windows, Windows Embedded, Linux, VxWorks, and QNX.
