2 SBC-350A User's Manual
Introduction
The half-size SBC-350A comes equipped with a 80386SX-40 CPU.
Also included on-board are two serial RS-232 ports, a bi-directional
parallel port, an IDE hard disk drive interface, a floppy disk controller
and a watchdog timer. The watchdog timer ensures that the CPU will
be reset if it stops due to a program or EMI problem, allowing the
SBC-350A to be used in stand-alone systems or in unattended environ-
ments. The SBC-350A’s industrial-grade construction ensures continu-
ous, reliable operation in harsh industrial environments at temperatures
up to 140
o
F (60
o
C).
We designed the SBC-350A with SBC (Single Board Computer)
applications in mind. It also incorporates a connector for PC/104
modules (Flat-panel/CRT VGA controller or Flash/RAM/ROM disk).
Built using CMOS technology, the SBC-350A consumes very little
power. Its four SIMM (Single In-line Memory Module) DRAM
sockets accept 256 KB, 1 MB or 4 MB SIMM modules for total on-
board memory of 1 to 16 MB.
You can also use this 4-layer CPU card to transform any system into a
16-bit 386 compatible computer, its all-in-one configuration freeing-up
valuable expansion slots. Its highly compact form and numerous
features make it an ideal cost/performance solution for high-end
commercial and industrial applications where high CPU speed and low
mean-time-to-repair are critical.
