WPCN384U
Legacy-Reduced SuperI/O with Two Serial Ports, Parallel
Port and GPIOs for Notebook and Docking Applications
General Description
The WPCN384U, a member of the Winbond LPC SuperI/O
family, is targeted for a wide range of notebook and docking
applications. The WPCN384U is PC2001 and ACPI compli-
ant, and features two Serial Ports, Parallel Port and General-
Purpose Input/Output (GPIO) support for a total of 21 ports.
The WPCN384U is an optimized solution for notebook
systems requiring no FIR Port, and for LPC-based docking
stations implementing an on-board SuperI/O.
