IBM PCM-6890B, All-in-One FC/Socket 370 Celeron Introduction, Highly integrated multi-media SBC

Introduction

The PCM-6890B is an all-in-one multi-media Celeron Pentium III processor based single board computer (SBC) with a 32-bit PCI audio controller, a PCI Flat Panel controller, a PCI 100Base-Tx Ethernet interface, and one PCI expansion slot. When using an Intel Pentium II/III processor, the PCM-6890B achieves outstanding performance that surpasses any other SBC in its class. In addition, the onboard SSD interface supports M-systems DiskOnChip 2000 series, memory capacity from 2 MB to 288 MB. This compact (only 5.75"“ x 8") unit offers all the functions of a single board industrial computer, but still fits in the space of a CD-ROM drive.

Onboard features include four serial ports (three RS-232, one RS- 232/422/485), one multi-mode parallel (ECP/EPP/SPP) port, connec- tor for two USB (Universal Serial Bus) ports, a floppy drive controller, and a keyboard/PS/2 mouse interface. The built-in high speed PCI IDE controller supports Ultra DMA/33 mode. Up to two IDE devices can be connected, including large hard disks, CD- ROM drives, and tape backup drives, etc.

The PCM-6890B also features power management to minimize power consumption. It complies with the ACPI standard and supports three types of power saving features: Doze mode, Standby mode, and Suspend mode. In addition, the board's watchdog timer can automatically reset the system or generate an interrupt in case the system stops due to a program bug or EMI.

Highly integrated multi-media SBC

The PCM-6890B is a highly integrated multi-media SBC that combines audio, video, and network functions on a CD-ROM drive size single computer board. It provides 32-bit half-duplex, 16-bit full-duplex, integrated 3D audio and up to 1024 x 768 resolution @ 64K colors with on-chip 2MB SDRAM display memory. Major onboard devices adopt PCI technology to achieve outstanding computing performance when used with Intel Celeron level processors, making the PCM-6890B one of the world's smallest and most powerful all-in-one multimedia boards.
