The F85226AF is a LPC to ISA Bridge IC for new generation chipset which is no support for ISA bus and slots. However the demand of ISA devices still exists. Therefore LPC to ISA Bridge IC is necessary to be used for new chipset system. The F85226AF is the best selection even though there is the PCI to ISA Bridge for supporting ISA device, because the issue of package size is critical for layout requirement. Follows the point at these issues, the F85226AF is optimal solution for the non-ISA chipset, the package of F85226AF will be the best chosen for economic solution and save the layout size of Motherboard.

The F85226AF absolutely meets LPC spec. 1.1 and supports fully ISA interface. Provides multi-ISA compatible slots without buffering and supports ISA parallel IRQ transfer to serial IRQ by IRQ Serialier. The F85226AF also provides programmable general purpose I/O pins for user. It is completely LPC to ISA bridge specialized chip.
