AMD-powered SBC keeps its cool without a fan

Edited by the Electronicstalk editorial team Apr 5, 2007

The PPM-GX is a PC/104-Plus compatible single board computer based on the low-power high-integration AMD GX500 processor.

WinSystems has introduced the 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 -40 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 yet it measures only 90 x 96mm.

PPM-GX will run x86-compatible software for space- and power-limited embedded designs.

It is targeted for the industrial telecommunications, homeland security, transportation, data communication, MIL/COTS and information appliance markets.

The PPM-GX is based on the AMD GX500 1W processor.

It is a Pentium-class CPU with an x86-native instruction set and 32Kbyte of integrated L1 cache that efficiently runs Windows CE, Windows XP embedded, Linux, and other x86-compatible operating systems such as VxWorks and QNX.

The PPM-GX supports up to 512Mbyte of SDRAM.

The PPM-GX also offers support for both rotational and solid state disks.

Two floppy disk drives and two UltraDMA 66 IDE drives can be connected.

Plus there is a socket for a CompactFlash card which can support up to an 8Gbyte device.

This solid state disk solution is a viable alternative for fragile floppy and/or hard disk drives for use with harsh environmental applications.

A high-performance 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 peripheral 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 that are available from vendors worldwide.

The PPM-GX draws typically 1.5A at +5V (8W) during normal operation.

Delivery is from stock to three weeks with a list price of US $495.
