Parvus has released four new PC/104 form-factor embedded processor modules based on Intel's new ULV Celeron Tualatin processor and 815E chipset. Three of the modules target harsh mobile environments such as trains, buses, aircraft, and tanks, and are compatible with embedded Linux, according to the company.

The three PC/104-Plus models — the SpacePC 1450, 1451, and 1453 — incorporate an aluminum heat spreader plate on top (shown at right), enabling sealed embedded systems to reliably operate from -40 degrees Celsius to +85 degrees Celsius without a fan, according to Parvus. The company says it has performed extensive thermal analysis to ensure that components are not stressed by excessive temperature load when recommended mounting instructions are followed.

These three modules also include 256MB of RAM soldered directly onto the board. According to the Parvus, this guarantees RAM compatibility, further enhances thermal performance, and ensures operation under shock and vibration stress when used in mobile applications such as trains, buses, aircraft, and tanks.

The PCI-only PCI-104 form-factor SpacePC 1850 (shown at the top of the page) is aimed at more cost-sensitive applications having more “moderate thermal requirements.” It includes finned heatsinks on top of components, and supports up to 512 MB of SO-DIMM memory.

All four modules provide a similar complement of peripheral interfaces:

• USB — 1.1 on the 1450 and 1850, 2.0 on the 1451 and 1453
• VGA ouput; the 1850 adds LVDS outputs
• Ethernet — 10/100 on the 1450 and 1850, Gigabit on the 1451 and 1453
• Serial, audio, keyboard, mouse, IDE, etc.

A “limited quantity” of all four modules is now in stock, priced from $557 to $979 each in volume orders of 100+ units, according to the company.
