2 SBC-357 User Manual
Introduction
The SBC-357 is an all-in-one single board 386 computer with an
onboard flat panel/CRT SVGA controller. It packs all the
functions of an industrial computer and its display capabilities
onto a single, half-size card. This means the SBC-357 is your
absolute best solution for embedded applications.
The onboard ISA-Bus, flat panel/CRT SVGA controller uses the
CHIPS 65545 chipset with up to 1 MB of video memory (512KB
onboard). It supports various LCD types including TFT, STN,
Normal, and EL.
The SBC-357 supports the optional M-Systems DiskOnChip
2000 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-357 also features three high speed RS-232 serial ports,
and one RS-232/422/485 serial port with 16C550 UARTs, one
bidirectional SPP/EPP/ECP parallel port, and a floppy drive
controller, all onboard.
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.
All configuration is done through software. A single Flash chip
holds the system BIOS, VGA BIOS, and the network boot ROM
image. This minimizes the number of chips and eases configura-
tion. You can change the display BIOS or install a boot ROM
simply by programming the Flash chip.
The SBC-357 supports 5 V EDO or FP 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 up to 32 MB of DRAM using the most
economical combination of SIMMs.
