Description

Overview
The Ocelot is a compact, rugged, single board computer (SBC) which features Intel’s 45 nm Z5xx Atom processor designed specifically for embedded applications. This compact SUMIT-104 SBC is ideal for defense, aerospace, medical device, robotics, and factory automation applications where high-performance, fanless, extended temperature operation is required.

Based on the industry standard PC/104 footprint, the Ocelot features the SUMIT expansion interface. This provides OEMs with a stackable multi-board expansion interface that supports both high- and low-speed signals. This simplifies adding both standard and custom I/O boards to the system. The Ocelot expansion interfaces include PCIe, USB, LPC, SPI, SMBus, as well as ISA bus support for PC/104 modules.

Like all VersaLogic products, the Ocelot is designed to support OEM applications where high reliability and long-term availability are required. From application design-in to 5+ guaranteed years of production life, the Ocelot provides a durable embedded computer solution with an exceptional cost of ownership. The Ocelot is manufactured and tested to the highest quality standards and is fully RoHS compliant. Customization is available, even in low OEM quantities.

Details
Based upon Intel’s 45 nm Hi-k metal gate silicon technology, the Z5xx Atom processor offers very high performance (up to 1.6 GHz) with excellent power management capabilities.

The on-board features include gigabit Ethernet, three USB 2.0 ports, four serial ports, IDE interface, HD audio, and SPX expansion interface. An IDE-based Disk on Module site offers bolt-down, bootable flash storage. The highly-integrated processor facilitates fast on-board transfers, high-speed memory access, and integrated high-performance video with flat panel LVDS or optional analog video output. An SO-DIMM socket supports up to 2 GB of DDR2 RAM.

The SUMIT interface provides three x1 PCIe lanes, LPC, SPI, SMBus, and four additional USB channels. The PC/104 connector provides ISA bus compatibility for many off-the-shelf I/O boards. The pass-through versions provide PC/104 stack-down capability to support custom baseboards that may be larger than the Ocelot.

The Ocelot draws about 7W typically, but the built-in ACPI 2.0 power management allows the board to enter sleep mode for greater power savings (typically 1W between transactions).

Available in both standard (0 to +60C) and extended (-40 to +85C) temperature versions; the Ocelot meets MIL-STD-202G specifications for shock and vibration. The Ocelot supports reliable field operation with fanless operation and transient voltage suppression (TVS) for electrostatic discharge (ESD) protection.

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