First “Em-ITX” board uses Nano CPU

Mar 27, 2009 — by Eric Brown — from the LinuxDevices Archive — 4 views

Via Technologies announced the first board based on its new 170 x 120mm Em-ITX format. Based on Via's 1.0 or 1.3GHz Nano processor and VX800 media system processor, the fanless Via EITX-3000 targets ultra-thin, embedded systems that require extended temperature support, says the company.

Announced earlier this month, Via's “open industry standard” EM-ITX format offers dual I/O “coastlines,” plus an “Em-IO” expansion bus that supports optional add-on modules. Measuring about 6.7 x 4.7 inches, the format offers the same width as Via's Mini-ITX, but with the height of Via's smaller (120x120mm) Nano-ITX format. The rectangular shape allows dual “coastlines,” providing 19 percent more room for real-world connectors than if a square had been utilized, according to the company. (For more information on EM-ITX, see our previous coverage, here.)

The EITX-3000 board places the available 1GHz or 1.3GHz Nano (or 500MHz Via Eden) on the reverse side of the board, providing more room for passive cooling apparatus, says the company. The lack of a fan, along with the board's extended temperature range of 14 to 158 degrees F (-10 to 70 deg. C) makes the EITX-3000 especially suitable for “always-on” applications including high-end POS (point of sale/service), kiosks, ATMs, HMI (human machine interaction), factory automation, POI, and digital signage, says Via.

The Via processors are supported by a SODIMM socket that can handle up to 2GB of DDR2 RAM. The Via VX800 chipset is equipped with Via Chrome9 HC3 DX9 3D/2D graphics controller, which provides MPEG-2/4 and WMV9 decoding acceleration. The VGA connector supports up to 1920 x 1440 resolution, and the dual LVDS connectors, meanwhile, can drive 1280 x 1024-pixel displays, as well as dual independent displays, says the company.

Interfaces include dual gigabit Ethernet ports and six USB connections (two front-facing ports and four pin-header interfaces). Four on-board serial ports can be configured through BIOS selection, and other I/O includes SATA and CF interfaces, as well as options for upcoming Via-developed EM-IO expansion boards. The EITX-3000 is further equipped with an on-board DC-DC power converter with variable power input (DC 7V ~ 36V) that is said to support both AT and ATX modes. Although operating system (OS) support was not stated, Via's x86 products typically support Linux and Windows.

Specifications for the Via EITX-3000 are said to include:

Stated Daniel Wu, VP, Via Embedded, Via Technologies, “The VIA EITX-3000 adds the performance-per-watt advantages of the VIA Nano processor to create a truly compelling embedded board for high-end digital media systems.”


Samples of the EITX-3000 will be available to project customers in early May, says Via. The company will demonstrate the board at ESC Silicon Valley 2009, March 31-April 2, McEnery Convention Center, San Jose, Booth 15109. More information on Via's ESC plans may be found here.
