PCM-9575 User’s Manual 2
Chapter 1 Introduction
1.1 Introduction
The PCM-9575 is a VIA low-power Eden/Ezra processor single board
computer (SBC) with audio controller, a 4X AGP SVGA controller, a PCI
10/100Base-T Ethernet interface, one PCI slot, and one PC/104-Plus
expansion connector. The PCM-9575’s design is based on the EBX form
factor that provides support for PC/104 and PC/104-Plus module expan-
sion. The EBX form factor also provides a convenient connector layout
for easy assembly, more efficient cable connections and better overall
embedded system integration. When using an Intel® Pentium® III pro-
cessor, the PCM-9575 achieves outstanding performance that surpasses
most SBCs in its class. 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 5.25“ floppy drive.
On-board features include, four serial ports (three RS-232, one RS-232/
422/485), one multi-mode parallel (ECP/EPP/SPP) port, two USB (Uni-
versal Serial Bus) ports, a floppy drive controller, and a keyboard/PS/2
mouse interface. The built-in high-speed PCI IDE controller supports
both PIO and UDMA/100 bus master modes. Up to four IDE devices can
be connected, including large hard disks, CD-ROM drives, and tape
backup drives.
The PCM-9575 features power management to minimize power con-
sumption. It complies with the “Green Function” standard and supports
Doze, Standby and Suspend modes. In addition, the board‘s watchdog
timer can automatically reset the system or generate an interrupt if the
system stops due to a program bug or EMI.
Highly integrated multimedia SBC
The PCM-9575 is a highly integrated multimedia SBC that combines
audio, video, and network functions on a single computer board the size
of a 5.25" floppy drive. It provides 16-bit half-duplex, 8-bit full-duplex,
integrated 3D audio, and up to 1024 x 768 resolution @ 16.8 M colors
with 8/16/32MB system memory. Major on-board devices adopt PCI
technology, to achieve outstanding computing performance when used
with Intel® Pentium® processors. The PCM-9575 also supports TV-out
that supports NTSC/PAL format for multimedia applications.
