Introduction

The SBC-556/L is an all-in-one single board Pentium computer card.
With an onboard flat panel/CRT SVGA controller, the SBC-556/L
packs all the functions of an industrial computer and its display
capabilities onto a single, half-size card. This means the SBC-556/L is
your absolute best solution for embedded applications.
The onboard PCI-bus, flat panel/CRT SVGA controller uses the CHIPS
69000 chipset with 2 MB of SDRAM built in chip. This chipset, used
with local PCI-bus, is a 64-bit graphics engine. Excellent for display-
intensive applications, this card supports various LCD types, includ-
ing TFT, DSTN, MONO, and EL.
Another feature of the SBC-556/L is the inclusion of a high speed,
local bus IDE controller. This controller supports (through ATA PIO)
mode 3 and mode 4 hard disks, and Ultra DMA/33, enabling data
transfer rates up to 33 MB/second. Up to two IDE devices can be
connected, including large hard disks, CD-ROM drives, tape backup
drives, or other IDE devices.
Onboard features include two high-speed RS-232 serial ports with
16C550 UARTs, one bidirectional SPP/EPP/ECP parallel port, and one
floppy drive controller. In addition, the SBC-556/L includes an extra
512 KB of second level on-board cache memory.
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 stand alone systems.
The SBC-556/L supports 5V EDO DRAM. It also provides two 72-pin
SIMM (Single In-line Memory Module) sockets for its onboard
system DRAM. These sockets give you the flexibility to configure
your system from 8 MB to 128 MB of DRAM using the most
economical combination of SIMMs.
