Overview
The AP53 is a high-performance Pentium
-based system board that utilizes
the PCI/ISA architecture. It integrates the Intel 430HX PCIset, a super I/O
controller, a PCI mode 4 enhanced IDE controller with bus master support and
a 256-KB pipelined-burst cache to enhance system performance. It also has
four single in-line memory module (SIMM) sockets that allow memory
expansion up to a maximum of 512 MB.
One main feature of AP53 is the green power-management function that
extends energy conservation from system components to display monitor. It
complies with the power-saving standards of the U.S. Environmental Protection
Agency (EPA) Energy Star program.
The AP53 board measures 220 mm x 250 mm and may come with or without a
voltage regulator module (VRM). The VRM enables the board to support future
2.5V processors.
