Chapter 1 Introduction
1.1 Introduction
The PCM-9371 is a Ultra low voltage Intel Celeron or Low voltage Intel
Pentium III processor single board computer (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-9371's design is based on the 3.5" HDD form factor that provides a
convenient connector layout for easy assembly, more efficient cable con-
nections and better overall embedded system integration. When using a
ULV Intel processor, the PCM-9371 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-9371 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 ultra low voltage (ULV) Intel Celeron
or low voltage (LV) Intel Pentium III Micor-FCBGA processor. The ULV
Intel processor uses advanced 0.13µ CMOS technology with on-die pri-
mary 16-Kbyte instruction and write-back data cache and 256-Kbyte with
Advanced Transfer architecture cache. This board can operate without a
fan at temperatures up to 60° C (140°F) and typically consumes under
13.5 Watts while supporting numerous peripherals. This SBC includes a
4X AGP controller, 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 supports the PC/104 interface for ISA module upgrades. Other
on-board features include an LPT, 2 USBs, and 2 serial ports: 1 RS-232,
