PCM-9373 User’s Manual 2
Chapter 1 Introduction
1.1 Introduction
The PCM-9373 is a VIA low-power Eden processor single board com-
puter (SBC) with audio controller, a 4X AGP SVGA controller, a PCI 10/
100Base-T Ethernet interface, 2 Channel LVDS interface, and one PC/
104 expansion connector. The PCM-9373’s design is based on the 3.5"
HDD form factor that provides a convenient connector layout for easy
assembly, more efficient cable connections and better overall embedded
system integration. When using a VIA Eden processor, the PCM-9373
achieves outstanding performance that surpasses most SBCs in its class.
This compact (only 5.7" x 4") unit offers all the functions of a single
board industrial computer, but still fits in the space of a 3.5" floppy drive.
On-board features include, two serial ports (one 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-9373 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.
1.1.1 Highly integrated multimedia SBC
The real estate is well-packed on this tightly designed 3.5" single board
computer (SBC) with an onboard new VIA Embedded low power Eden
or C3 EBGA processor. The VIA Eden processor uses advanced 0.15µ/
0.13µ CMOS technology with 128KB L1 cache memory and 64KB L2
cache memory on die. This board can operate without a fan at tempera-
tures up to 60× C (140× F) and typically consumes under 12 Watts while
supporting numerous peripherals. This SBC includes a 4X AGP control-
ler, an AC'97 audio interface, a PCI Ethernet interface, and 2 channel
LVDS interface. Its design is based on the 3.5" SBC form factor that sup-
ports the PC/104 interface for ISA module upgrades. Other on-board fea-
tures include an LPT, 2 USBs, and 2 serial ports: 1 RS-232, and 1 RS-
232/422/485. The SSD solution supports CompactFlash™ cards Type I
and Type II.
