Embedded PC/104+ ModuleRoHS-compliant



The Tomcat single board computer features the ultra-low power DMP Vortex86DX processor. Based on the PC/104-Plus industry standard form factor, the Tomcat supports PCI and ISA stackable expansion boards. With mid-range performance (800 MHz) and ultra-low power consumption (3.0W typ.), the Tomcat is well suited to size, weight, and power constrained applications. With no moving parts (fanless operation), full industrial temperature rating, soldered-on RAM, and a compact rugged form factor, it is ideal for operation in harsh, mobile, and/or remote environments.

The Tomcat is "headless". It is designed for applications that do not require any type of video output.

Like all VersaLogic products, the Tomcat is designed to support OEM applications where high reliability and long-term availability are required. From application design-in support, to its extended production lifecycle, the Tomcat provides a durable embedded computer solution with an excellent cost of ownership. The Tomcat is manufactured and tested to the highest quality standards and is fully RoHS compliant. Customization is available, even in low OEM quantities.

VersaLogic products are designed for use by OEMs working in a variety of market applications: Aerospace, Defense, Energy, Industrial, Security, Medical, Military, Robotics, and Transportation. Anywhere that the need for superb quality and high-performance embedded computing exists, applications include: automation, avionics, gateway, in-vehicle, monitoring, simulation, and vision.

VersaLogic delivers extremely reliable standard and customized embedded computers backed with unsurpassed service and the highest availability in the market. VersaLogic exists to exceed customers' product, service, support and delivery needs - whenever and wherever the need arises.
