Rugged ETX module for industrial-strength applications

23 February 2005 Computer/Embedded Technology

Ampro Computers' ETX 700 computer-on-module (COM) allows system OEMs to use ETX form factor modules in harsh environment applications.

This means that manufacturers of medical, military, transportation and industrial products, among others, can now successfully use ETX-based designs for applications which require industrial temperature specifications as well as resistance to shock, vibration and humid and corrosive conditions.

"Ampro is responding to a cry for a rugged, reliable ETX module," said Joanne Williams, president and CEO of Ampro. "We used our time-tested PC/104 and EBX design and manufacturing technology to build a truly rugged ETX product that operates across an extended -40 to +85°C temperature range, provides high resistance to vibration and shock, and is available with conformal coating."

"One of the techniques Ampro employs is the use of a 50% thicker PCB, the same thickness as our LittleBoard and EnCore products," said Paul Rosenfeld, CTO of Ampro. "The thicker board provides extra rigidity needed to avoid flexing the board during installation on a baseboard as well as extra copper to smoothly dissipate heat throughout the module. Ampro uses temperature and voltage margin testing early and throughout the design phase to ensure that the products meet the demands of rugged applications."

Ampro's ETX 700 features a choice of 933 MHz P-III, 650 MHz Celeron, or 400 MHz Celeron processors, plus all the component subsystems expected in a state-of-the-art COM. Supporting up to 512 MB RAM, the module also includes thermal monitoring and power management functions.

Onboard I/O includes 10/100BaseT Ethernet controller and an advanced AGP 4X video controller with CRT and flat panel support. Up to 32 MB of video memory is accessible. Other onboard controllers provide AC97 sound, 4x USB, 2x full modem TTL serial ports (RS232/422/485 transceivers are added on the baseboard) and all standard PC architecture elements.
