High-performance Celeron on fanless PC/104 board

7 April 2004 Computer/Embedded Technology

Ampro's CoreModule 600 single board computer (SBC) operates from -40 to +85°C without a fan. The PC/104-Plus CoreModule 600 is a full-featured embedded computer using Intel's ultra low voltage Celeron processor with 256 KB internal L2 cache.

With this, Ampro says that system OEMs who require 5- to 10-year product availability, extended temperature, and/or conformal coating for their rugged application, now have a migration path from their earlier 486 and Pentium PC/104 modules without having to sacrifice reliability by adding a fan to their system.

"Ampro invented the PC/104 standard and co-founded the PC/104 Consortium to provide PC technology to the embedded systems market. By doing so OEMs reaped the benefits of long-term availability, low power dissipation, compact size, and high reliability under rugged conditions, which our military, medical, and industrial customers absolutely depend on," said Joanne Williams, president and CEO of Ampro. "This time we have outdone ourselves in bringing Celeron processors to this market without sacrificing size, power consumption, or compatibility with industry standards."

Ampro CTO, Paul Rosenfeld, added, "Our engineering, quality, operations, and test departments have worked extremely closely together to design a very dense board which is manufacturable and testable in high volumes, and has the same high level of quality and reliability our customers have come to expect from Ampro. The benefactors of their hard work are embedded systems OEMs who can now migrate up to Pentium III-class performance without having to worry about how to get the heat from a 20 W processor out of their enclosures. This is a very significant milestone in the history of the PC/104 market."

Intel's ultra low voltage (ULV) Celeron processors, based on the Tualatin core, offer embedded systems OEMs reduced power dissipation, twice the internal cache (256 KB), and faster front-side bus speed compared to the previous-generation Socket 370 processors based on the Coppermine core.

With Intel's power rating of only 4,2 W, which is 80% less than the 21,7 W rating of the Socket 370 Celeron at 366 MHz, Ampro says the Tualatin-based ULV Celeron processor at 400 MHz is ideal for the next-generation of high-performance PC/104-based embedded systems, where the degree of difficulty of the thermal design alone can make or break a project. This processor has much higher performance and lower power dissipation than the 266 MHz Pentium MMX processor, so the CoreModule 600 is an ideal migration solution for OEMs with I/O-rich systems based on the older MMX processor.
