Description

W83626F/W83626D 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 exist. For such case, W83626F is the best companion solution for the non-ISA chipset. Also the packages of W83626F 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 (Winbond LPC I/O) together with the set of W83626F is the complete solution.
