LPC to ISA I/F
The W83626F/W83626G is a transparent LPC-to-ISA bus conversion IC.
For the new generation Intel chipsets, and SiS Super South 960 which use the LPC bus, there is no support for ISA bus and slots. However, the demand of ISA devices still exists. For such case, the W83626F/G is the best companion solution for the non-ISA chipset. Also the packages of W83626F/G have been chosen to be the most economical solution for M/B board layout size and cost savings.
