Revision 1.0
WPCN385L
LPC-to-LPC Switch, Fast Infrared Port, Serial Port and GPIOs
General Description
The WPCN385L, a member of the Winbond LPC SuperI/O
family, is targeted for a wide range of portable applications.
The WPCN385L is PC2001 and ACPI compliant, and fea-
tures an LPC-to-LPC Switch with hot plugability, a Fast Infra-
red port (FIR, IrDA 1.1 compliant), Serial Port and General-
Purpose Input/Output (GPIO) support for a total of 18 ports.
The WPCN385L enables glueless implementation of an
LPC-to-LPC Switch between the motherboard LPC bus and
the Docking Station, and supports hot insertion and hot re-
moval.
Outstanding Features
■ Pin and software compatible with the Winbond 87382
■ LPC-to-LPC Switch with hot plugability, enables LPC
devices in the Docking Station to be connected to the
Main LPC Bus, thus reducing the number of signals re-
quired through the Docking Station connector
■ Fast Infrared Port (FIR)
■ Serial Port
■ LPC bus interface, based on Intel’s LPC Interface
Specification Revision 1.1, August 2002 (supports
CLKRUN and LPCPD signals)
■ PC2001 and ACPI Revision 3.0 compliant
■ 18 GPIO ports, including 11 with IRQ assertion capa-
bility
■ Two testability modes (XOR Tree and TRI-STATE®
device pins).
■ 5V tolerant and back-drive protected pins (except LPC
bus pins)
■ 48-pin LQFP package
