1. GENERAL DESCRIPTION
The W83628AG is a PCI-to-ISA bus conversion IC. The W83629AG is a condensed centralizer IC for
IRQ and DMA control. W83628AG and W83629AG together form a complete set for the PCI-to-ISA
bridge.
For the new generation Intel chipsets featuring LPC bus but not supporting ISA bus and slots, the
W83628AG plus the W83629AG are the best companion solution for the non-ISA chipset. Also the
packages of the W83628AG (128-QFP) and the W83629AG (48-LQFP) are the most cost-effective
solution that minimizes the M/B board layout size and cost.
For the new generation chipsets featuring LPC interface but not supporting ISA bus, the best and the
most complete solution will be the combination of the W83627 (Nuvoton LPC I/O) family and the set of
the W83628AG and the W83629AG.
