| Tiny embedded computer module packs Pentium punch |
Jan. 04, 2007
 CompuLab is shipping a tiny embedded computer module available with a Celeron or Pentium M processor clocked at 2GHz. The CM-iPM, which is meant to be used like a component, crams processor, graphics, networking, super-I/O, and PCI Express functions into a 2.75 x 3.5 inch footprint.

At 2.75 x 3.5 inches (70 x 90mm), the CM-iPM is marginally smaller than Kontron's 3.75-inch square (95 x 95mm) MicroETXexpress form-factor. It is also smaller than the 95 x 125mm COM Express standard promoted by Kontron, Intel, and others. And, of course, it is significantly smaller than PC/104 Express, a variant of PC/104 that adds PCI Express.
The CM-iPM is touted as a rugged processor module, with all components soldered on, including memory. Three 140-pin connectors with a pin pitch of 0.6 mm (shown in the photo below) attach the module to custom baseboards. The connectors are rated for 50 insertion/removal cycles, according to CompuLab.

The CM-iPM dissipates between 10 and 30 Watts, depending on processor choice and CPU usage, CompuLab says. The module is available in three operating temperature ranges, including an extreme version said to be tested for stability with heatsink temperatures between -72 and 153 degrees F (-40 to 85 C).

Significant CM-iPM features include support for USB-based NAND flash drives up to 512MB, a PCI Express bus, and optional gigabit Ethernet. The module supports display resolutions up to 1920 x 1200, and offers a plethora of display connection technologies, including LCD, LVDS, CRT, and TV (DVI) interfaces.
