  1. 2009/07/22 W83626F - LPC TO ISA BRIDGE SET
GENERAL DESCRIPTION
W83626F/W83626D/W83626G is a transparent LPC-to-ISA bus conversion IC.
For the new generation Intel chipset Camino and Whitney, SiS Super South 960, featuring LPC bus, there is no support for ISA bus and slots. However, the demand of ISA devices still exists. For such case, W83626F/G is the best companion solution for the non-ISA chipset. Also the packages of W83626F/G had been chosen to be the most economic solution for save the M/B board layout size and cost.
For the new generation chipset featuring LPC interface and support no ISA bus, W83627HF/HG (Winbond LPC I/O) together with the set of W83626F/G is the complete solution.
