2 SBC-456/456E User Manual
Introduction
The SBC-456/456E is an all-in-one single board 486 computer with an
onboard flat panel/CRT SVGA controller and PCI Ethernet interface
(SBC-456E). It packs all the functions of an industrial computer and
its display capabilities onto a single, half-size card. This means the
SBC-456/456E is your absolute best solution for embedded applica-
tions.
The onboard PCI-bus, flat panel/CRT SVGA controller uses the CHIPS
65550 chipset with up to 2 MB of video memory (onboard 1MB). This
chipset, used with the local PCI-bus, enables 32-bit graphic through-
put at up to 33 MHz. Excellent for display-intensive applications, it
supports various LCD types including TFT, STN, B/W, and EL.
The onboard Ethernet Realtek RTL 8029AS PCI bus Ethernet controller
supports remote boot ROM functions (SBC-456E only).
The SBC-456/456E supports the M-Systems DiskOnChip 2000 (option-
al) 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.
Another feature of the SBC-456/456E is the inclusion of a high speed,
local bus IDE controller. This controller supports (through ATA PIO)
mode 3 and mode 4 hard disks, enabling data transfer rates in excess of
11 MB/second. Up to four IDE devices can be connected, including
large hard disks, CD-ROM drives, tape backup drives, or other IDE
devices. The built-in, enhanced IDE controller provides a 4-layer, 32-
bit, posted write buffer and a 4-layer, 32-bit read-prefetch buffer to
boost IDE performance.
