Features - Aaeon SBC-400 User Manual

The SBC-400 is an all-in-one CPU card that supports L2 cache sizes
from 128 KB to 512 KB (32 KB x 8, 64 KB x 8, or 128 KB x 8). This
CPU card uses the M1489/M1487 chipsets, which accept Intel, AMD,
Cyrix, or other compatible 486-based CPUs. The SBC-400 is fully PC/
AT compatible, so your software will run without modifications.
On-board features include two high-speed serial ports (RS-232 and
RS-232/422/485) with 16C550 UARTs, one bi-directional parallel
port, and a floppy drive controller. If program execution is halted by a
program bug or EMI, the board's 16-stage watchdog timer can
automatically reset the CPU or generate an interrupt. This ensures
reliability in unmanned or stand-alone systems.
The SBC-400 is built with a high speed local bus IDE controller. This
controller supports (through ATA PIO) mode 3 and mode 4 hard disks,
which enable data transfer rates of over 11 MB/second. It connects up
to two IDE devices, including large hard disks, CD-ROM drives, tape
backup drives, etc. 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.
The SBC-400 supports 5V EDO DRAM. It also provides two 72-pin
SIMM (Single In-line Memory Module) sockets for on-board DRAM.
This gives you the flexibility to configure your system memory from 1
~ 128 MB using the most economical combination of SIMMs.
The SBC-400 also features power management to minimize power
consumption. It uses CMOS components and complies with the
"Green Function" standard.
If you need any additional functions, you can add industry-standard
PC/104 expansion modules. We provide numerous PC/104 modules to
meet your system requirements.
