Features - Aaeon SBC-555 Manual

The SBC-554V/555 is an all-in-one single board Pentium computer
incorporating the latest PISA Bus interface for SBC-554V, and one
ISA Bus for SBC-555. Unlike ISA Bus card, SBC-554V supports
PCI and ISA interface for user to connect PCI and ISA add-on cards.
With an on-board flat panel/CRT SVGA controller, the SBC-
554V/555 packs all the functions of an industrial computer and its
display capabilities onto a single, half-size card. This means the SBC-
554V/555 is your absolute best solution for embedded applications.
The on-board PCI-bus, flat panel/CRT SVGA controller uses the
CHIPS 65554 chipset with 2 MB of video memory on board. This
chipset, used with local PCI-bus, is a 64-bit graphics engine. Excel-
lent for display-intensive applications, this card supports various
LCD types including TFT, DSTN, MONO, and EL.
Another feature of the SBC-554V/555 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 33MB/second. Up to two IDE
devices can be connected, including large hard disks, CD-ROM
drives, tape backup drives, or other IDE devices.
On-board 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-554V/555 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 standalone systems.
The SBC-554V/555 supports 5V or 3.3V EDO DRAM. It also
provides two 72-pin SIMM (Single In-line Memory Module) sockets
for its on-board system DRAM. These sockets give you the flexibili-
ty to configure your system from 1 MB to 128 MB of DRAM using
the most economical combination of SIMMs.
