CHAPTER

2SBC-551/552 User Manual
Introduction
TheSBC-551/552is an all-in-one SingleBoardComputer(SBC)
capable of handling the Intel Pentium P54C, P55C (MMX),AMD
K6,aswell as theCyrix6x86(M1) and 6x86MX(M2)CPUs.
Reliability,performance, flexibility, andadequateexpansion
capabilities are essential qualities for SBCs and their embedded
applications and the SBC-551/552 provides all of these.
The Smart Temperature Control technology (LM75 chip) monitors
the CPU temperature and automatically slows down the CPU
frequency when the CPU temperature exceeds a specified safe
range, helping your system recover from abnormal temperature
fluctuations.
TheSBC-551/552 supports the M-Systems DiskOnChip 2000
(optional) which is a new generation of high performance single-
chip Flash Disk. It provides a Flash Disk (as a BIOS expansion)
which doesn't require any bus, slots, or connectors. It is also the
optimal solution for Single Board Computers because of its small
size, easy integration, plug-and-play functionality, and its low
power consumption. The DiskOnChip is available in capacities
from 2MB to 72MB and fits in a standard 32-pin DIP socket.
The SBC-551/552 also includes a high speed, local bus IDE
controller which supports (through ATA PIO) mode 3 and mode 4
hard disks, Ultra DMA/33 (data transfer rates up to 33MB/sec) and
up to 2 IDE devices.
Onboard features include one high speed RS-232 serial port, one
RS-232/422/485serialport with 16C550 UARTs,onebidirectional
SPP/EPP/ECP parallel port, and a floppy drive controller. In
addition to the 486's 16 KB of onchip cache memory, the SBC-551/
552includes an extra 512 KB of pipeline-burst L2cachememery.
If program execution is halted by a program bug or EMI, the board's
watchdog timer can automatically reset the CPU or generate an
interrupt. This ensures reliability in unmanned or standalone
systems.

Chapter 1 General Information 3
TheSBC-551/552providestwo72-pinSIMM(SingleIn-line
Memory Module) sockets for intalling onboard system DRAM.
These sockets give you the flexibility to configure your system
from 4 MB to 128 MB of DRAM using the most economical
combination of SIMMs.

Setting jumpers
By setting the jumpers, you can configure your card to match the
needs of your specific applications. A jumper is the simplest kind
of electric switch. It consists of two metal pins and a small metal
clip (often protected by a plastic cover) that slides over the pins to
connect them. To close a jumper you connect the pins with the
clip. To "open" a jumper you remove the clip. Sometimes a jumper
will have three pins, labeled 1, 2, and 3. In this case you would
connect either pins 1 and 2 or 2 and 3.
The jumper settings are schematically depicted in this manual as
follows:
A pair of needle-nose pliers may be helpful when working with
jumpers.
If you have any doubt about the best hardware configuration for
your applications, contact your local distributor or sales represen-
tative before you make any changes.
