The Tiger is an embedded single board computer (SBC) featuring a high-performance Intel Atom Z5xx processor. Based on the PC/104-Plus industry standard form factor, the Tiger supports both PC/104 and PC/104-Plus stackable expansion boards. With its combination of high performance (up to 1.6 GHz), low power consumption (6W typ. while executing code), and fanless operation, the Tiger is an ideal embedded computer solution for space, weight, and power (SWaP) constrained embedded applications in industrial, energy, defense/aerospace, medical, and robotics markets.

Like all VersaLogic products, the Tiger 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 Tiger provides a durable embedded computer solution with an excellent cost of ownership. The Tiger is manufactured and tested to the highest quality standards and is fully RoHS compliant. Customization is available, even in low OEM quantities.

Driven by an Intel Atom Z5xx processor designed specifically for embedded applications, the Tiger runs completely fanless at up to 1.6 (commercial temperature) or 1.33 GHz (industrial temperature). Enhanced Intel SpeedStep technology provides dynamic processor frequency scaling to meet instantaneous performance needs while minimizing power draw and heat dissipation. This allows users to fine-tune the balance between power conservation and performance to suit their application needs. Enhanced low-power states, including the new C6 state (Deep Power Down Technolog), allow designers to further minimize overall power consumption.

The integrated graphics core of the Atom Z5xx processor supports advanced 3D graphics and high-definition video decode. Video output is provided through an integrated LVDS flat panel video interface and optional analog VGA support.

Tiger’s standard on-board features include gigabit Ethernet with network boot capability, SO-DIMM socket for up to 2 GB DDR2 RAM, seven USB 2.0 ports, four serial ports, IDE controller with support for two devices, HD audio, and a Disk on Module (DOM) socket for removable flash storage. PC/104-Plus expansion provides plug-in access to a wide variety of industry standard expansion modules. VersaLogic’s SPX expansion interface provides access to cost-effective plug-in analog, digital, CANbus, and custom I/O solutions.

Available in both industrial (-40 to +85C) and commercial (0 to +60C) temperature versions; the Tiger 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 which is critical in many OEM applications.

The Tiger features an embedded BIOS with OEM enhancements from Phoenix Technologies. The field-reprogrammable BIOS supports custom defaults and the addition of firmbase applications for security processes, remote booting, and other pre-OS software functions. The Tiger is compatible with a variety of popular operating systems including Windows, Windows Embedded, Linux, VxWorks, and QNX.
