Atom-powered COM Express module can be frozen, baked

Dec 1, 2011 — by LinuxDevices Staff — from the LinuxDevices Archive — 2 views

Kontron announced a COM Express Compact module that features Intel's dual-core Atom D525 processor, up to 4GB of DDR3 memory, and the ability to work in temperatures ranging from -40 to 185 deg. F. The microETXexpress-PV-XT includes PCI and PCI Express expansion, gigabit Ethernet, LVDS and VGA video outputs, eight USB 2.0 ports, and three SATA ports.

Describe it as "new" Kontron might, but the microETXexpress-PV-XT really isn't much different from the microETXexpress-PV announced Nov. 22. (And that module wasn't much different from an earlier version the company announced with the same name in March 2010: It just gained a different Atom processor and a higher RAM limit.)

All that has changed now for this 95 x 95mm (3.75 x 3.75) microETXexpress format (a.k.a. COM Express Compact) module is its operating range. The standard microETXexpress-PV is operable from 32 to 140 deg. F; the revised -XT version may be chilled down to -40 deg. F or baked up to 185 deg. F.

Kontron offers both active (fan-equipped) and passive heat sinks for the microETXexpress-PV-XT. The company's data sheet doesn't specify under what circumstances the fan might be required, however, except to say that the module's extended temperature range requires a "proper cooling solution."

The original microETXexpress-PV from 2010 used Intel's Atom N450 or D410 (both single-core) and dual-core D510, which can only work with up to 2GB of DDR2 memory. The 2011 models switch to the 1.8GHz, dual-core Atom D525, allowing the module to accept up to 4GB of DDR3 memory in its two DIMM slots.

Kontron's microETXexpress-PV-XT

Kontron again says the microETXexpress-PV-XT includes 18-bit LVDS graphics and supports VGA resolutions up to 1400 x 1050 pixels. Compatible with the COM Express Type 2 pin-out, the module serves up three SATA ports, eight USB ports, and a gigabit Ethernet port. The module also supplies 32-bit PCI expansion, five PCI Express x1 lanes, I2C, SPI, and LPC, according to the company.

  • Processor — 1.8GHz Intel Atom D525
