Overview
The Cheetah single board computer reaches a new level of sophistication for embedded product
technology, integrating very high performance with an expanded feature set on the compact
and rugged PC/104-Plus
form factor. The advanced design of the Pentium M processor makes
it suitable for a wide range of higher-end applications such as security systems, telematics,
UAVs, and sophisticated communications equipment.
An impressive amount of functionality is packed into the 2-board set, including 10/100 Ethernet,
two USB 2.0 ports, two COM ports, LPT, IDE, audio, and high-resolution video output. It
includes a CompactFlash socket for on-board bootable media storage, TVS devices on the
user I/O for enhanced ESD protection, and a watchdog timer to control application run-away
conditions. The Cheetah accommodates up to 1 GB DDR system RAM in a high-retention
SO-DIMM socket.
Like all VersaLogic products, this small, powerful SBC is designed to support OEM applications
where high reliability and long-term availability are required. From application design-in to
5+ years production life, its quality and longevity provide a cost-effective, long-term solution.
The Cheetah is manufactured and tested to the highest quality standards and is backed by a
two-year limited warranty. Customization is available in as few as 100 pieces.

Details
The Cheetah’s Pentium M processor provides outstanding performance of 1.0 GHz while drawing
less than 12 watts of power. The processor and chipset solution relies on three separate chips:
the processor, a graphics and memory controller hub that provides fast RAM access and video
output, and an I/O hub that provides PCI, IDE, USB, and audio functionality.
The Extreme Graphics 2 video built into the chipset offers outputs for LVDS flat panels and
analog (CRT) monitors at resolutions up to 2048 x 1536. It supports 24-bit color, very fast
rendering, and MPEG-2 decoding for full motion video. Video RAM is allocated from system
memory (up to 64 MB).
With two COM ports, two USB ports (2.0), 10/100 Ethernet, LPT port, and IDE interface,
the Cheetah offers more I/O options than other similar-sized SBCs. In addition, PC/104 and
PC/104-Plus
connectors provide support for many off-the-shelf expansion boards for added
system functionality with minimal space requirements. The Cheetah also includes a number
of reliability-enhancing features such as a watchdog timer and TVS devices.
