Atom-based EPIC board ready to freeze or fry

May 3, 2011 — by Eric Brown — from the LinuxDevices Archive — 2 views

WinSystems announced an EPIC-format single board computer (SBC) that operates in temperatures of -40 to 158 deg. F (-40 to 70 deg C). Offered with a 1.66GHz Intel Atom N450 or dual-core D510, the EPX-C380 ships with up to 2GB DDR2 SDRAM, plus CompactFlash, SATA, PC-104-Plus, Mini PCI Express, gigabit Ethernet, USB, serial, and GPIO connectivity, says the company.

The EPX-C380 carries on a lineage of WinSystems extended-temperature, EPIC format SBCs, dating back to the Via C3-based EPX-C3 in 2004. (The last EPX board covered here was the Celeron-M-based EPX-855-G announced in 2008.)

WinSystems was one of the originators of the EPIC (Embedded Platform for Industrial Computing) standard, which defines a board measuring 6.5 x 4.5 inches (165 x 115mm) — the dimensions of the new EPX-C380. This latest EPX board is designed for applications such as medical, COTS/military, security, transportation, pipeline, and machine control, says the company.

The EPX-C380 comes in two versions — an EPX-C380-S model with a single-core Intel Atom N450, and the EPX-C380-D with a dual-core Atom D510. Both of these Pineview processors are clocked to 1.66GHz, and they include both integrated graphics and a separate ICH-8M I/O hub controller.

The two models have their own web pages, but as far as we can see are otherwise identical except that the D510 adds an extra 23 grams to the weight of the "D" model!

The EPX-C380 incorporates both VGA and LVDS display interfaces, with respective resolutions of 1400 x 1050 and 1366 x 768 pixels, says WinSystems. The SBC is said to support up to 2GB of soldered DDR2 667MHz system memory. A CompactFlash socket is available, as well as the option of 512MB to 2GB onboard flash, says the company.

The EPX-C380 is equipped with two gigabit Ethernet ports, two SATA channels, eight USB 2.0 ports, and four RS-232/422/485 asynchronous serial channels, says WinSystems. Other I/O is said to include 48 lines of digital I/O and an LPT interface. Expansion is available via PC/104-Plus and mini-PCI  Express (PCIe) connectors, says WinSystems.

The SBC supports temperatures ranging from -40 to 158 deg. F (-40 to 70 deg C), says the company. Power consumption is said to run typically at 1.9mA.
