PPM-GX SBC from WinSystems

WinSystems has introduced PPM-GX, a PC/104-plus-compatible single board computer (SBC) based on the low-power, high-integration AMD GX500@1W processor. This SBC operates throughout the temperature range of -40C to 85C without the need for a fan. The board integrates the CPU, video, Ethernet, USB, COM, LPT, mouse, audio and keyboard controllers onto one board. PPM-GX will run x86-compatible software for space- and power-limited embedded designs. It is targeted for the industrial telecommunication, homeland security, transportation, data communication, MIL/COTS and information appliance markets.

The board's processor is a Pentium-class CPU with an x86-native instruction set and 32Kbytes of integrated L1 cache that efficiently runs Windows CE, Windows XP embedded, Linux and other x86-compatible operating systems including VxWorks and QNX. It supports up to 512Mbytes of SDRAM and assists rotational and solid-state disks. Two floppy disk drives and two UltraDMA 66 IDE drives can be connected. There is a socket for a CompactFlash card which can support up to an 8Gbyte device. This solid-state disk design is an alternative for fragile floppy and/or HDDs for use with harsh environmental applications.

A graphics controller is integrated into the AMD GX 500@1W processor that supports both CRT and flat-panel displays. It can support resolutions up to 1600 x 1200 (CRT) or up to 1280 x 1024 (flat panel). The PPM-GX also includes an Intel 10/100 Ethernet controller, four 16C550-compatible UARTs and two USB ports. Other functions supported include a floppy disk controller, IDE hard disk interface, PS/2 keyboard controller, line printer (LPT) interface, mouse port, battery-backed real-time clock, precision power-fail reset circuit and programmable watchdog timer. Additionally, it supports PC/104 or PC/104-Plus expansion I/O modules. The PPM-GX draws typically 1.5A at 5V during normal operation.

The SBC is available for $495.
