ESD Precautions
Integrated circuits on computer boards are sensitive to static
electricity. To avoid damaging chips from electrostatic
discharge, observe the following precautions:
Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them.
Before handling a board or integrated circuit, touch an unpainted
portion of the system unit chassis for a few seconds. This helps to
discharge any static electricity on your body.
Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.

Introduction
1.1 General Description
The SBC82400 is the ultimate cost-effective solution of 486-level
embedded half card. The SBC82400 comes with an embedded high-
performance STPC Consumer-II microprocessor and 32MB SDRAM
onboard. For maximum performance, it also has one optional DIMM
socket that can support up to 128 MB memory.
Its major onboard features include a DOC®2000 socket, a
Compact Flash socket, an IDE interface, a parallel port, two
serial ports (RS-232 and RS-232/422/485) a RJ-45 for fast
Ethernet and a mini-DIN PS/2 connector for keyboard and
mouse. A SVGA display controller, which integrated in
Consumer-II microprocessor, allows the CRT display resolution
up to 1280 x 1024 @ 256 colors.
