Atom-powered PC/104+ SBC targets display devices

Aug 28, 2009 — by Eric Brown — from the LinuxDevices Archive — 2 views

Win Enterprises announced a fanless, Linux-compatible PC/104+ single board computer (SBC) aimed at display-oriented embedded applications. The MB-73200 is equipped with an Intel Atom Z5xx CPU clocked at 1GHz or 1.6GHz, dual Ethernet ports, and SATAII and CompactFlash interfaces, says the company.

The MB-73200 is designed for space-limited applications such as medical, interactive kiosk, human-machine interface (HMI), in-vehicle infotainment, gaming, and industrial control, says Win Enterprises. Adhering to the PC/104+ form factor,  backward-compatible to PC/104, the SBC enables additional I/O, starting with an optional high definition (HD) audio card offered by the company.

The MB-73200 is available with choice of a 1.1GHz Intel Atom Z510 or 1.6GHz Z530 CPU, and is further equipped with up to 2GB of DDR2 memory, says Win Enterprises. The MB-73200's Intel System Controller Hub US15W chipset supports 3D graphics, HD video decode, and image processing, says the company. The chipset is touted as supporting CRT resolution of up to 2048 x 1536, as well as single-channel 24-bit LCD/LVDS, and dual simultaneous displays.
