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 (3.1W 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 5+ year production life guarantee, 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.

Driven by a DMP Vortex86DX processor, the Tomcat runs at 800 MHz. The 32-bit CPU integrates memory and I/O controller hub functions to provide an x86-compatible single-chip solution with ultra-low power consumption.

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 +70C) and industrial (-40 to +85C) 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.
