The LPM-LX800-G from WinSystems (Arlington,TX) is a high-integration STD Bus single board computer (SBC) that incorporates the low power, AMD Geode™ LX800MHz 0.9W CPU. The LPMLX800- G can be populated with up to 1 GByte of system DRAM and up to 16 GBytes of CompactFlash. A high-performance video engine is onboard that supports LCD and CRT displays simultaneously. An Intel 82551ER, 32-bit PCI 10/100 Ethernet controller supports networking. Further I/O support includes four USB 2.0 ports with in-rush and over-current protection, four independent RS- 232/422/485 full-duplex serial UARTs, 48-lines of TTL-compatible digital I/O, and AC97 audio.

The LPM-LX800 contains the core logic to provide PC-compatibility for the I/O and bus interface logic including the UDMA100 controller for hard disks, keyboard/mouse controller, LPT interface, real-time clock, and interrupt controller. A precision power-fail reset circuit, activity LED, PC/104-Plus expansion, and watchdog-timer are also included. The 4.5" × 7.0" STD Bus board operates as a standalone SBC, or users can add off-the-shelf or user-designed IEEE 961 STD Bus cards, PC/104, or PC/104-Plus expansion I/O modules to match their exact application. The RoHS-compliant LPM-LX800 will operate over the industrial temperature range of -40° to +85°C and does not require a fan.
