AP-545L / 1
INTRODUCTION
The AP-545L is a half-size ISA single board computer for Socket 7 processor that is
using the SIS’s BGA chipset SiS5582 that support the Ultra DMA-33 for faster hard
drive, and USB function. For boosting operation, this motivated card also supports
sockets for a Flash Disk and one DIMM memory module. It offers the function of an
industrial computer on a single board with on-board 2
nd
level cache RAM of 512KB for
maximum performance.
Take note that the AP-545L is a high power & full engine SBC with on-board function in
the LCD/VGA display of resolution up to 1280 x 1024 at 256 colors. It provides the
primarily elements for building an IBM PC/AT compatible computer for a wide variety of
applications with system integration. The AP-545L is fully compatible with the IBM
PC/AT which means virtually all the software written for the IBM PC/AT will run on the
AP-545L SBC.
Other on-board features include two serial ports (one each of RS-232 and
RS-232/422/485), one multi-mode parallel (ECP/EPP/SPP) port, a floppy drive
controller and a keyboard interface and a PS/2 mouse interface. The built-in one high
speed PCI IDE controller supports both PIO and bus master modes. Up to two IDE
devices can be connected, including large hard disks, CD-ROM drives, tape backup
drives and other IDE devices. Its 6-layer printed circuit board combines with
noise-tolerant and low power consumption CMOS technology applied on the board
makes AP-545L able to withstand any harsh industrial environments very well.
