PC87382
LPC-to-LPC Switch for Docking Stations, with Fast
Infrared Port, Serial Port and GPIOs
General Description
ThePC87382,amemberoftheNationalSemiconductorLPC
SuperI/O family, is targeted for a wide range of portable ap-
plications.ThePC87382isPC2001andACPIcompliant,and
features an LPC-to-LPC Switch with hot plugability, Fast In-
frared port (FIR, IrDA 1.1 compliant), Serial Port, and Gener-
al-Purpose Input/Output (GPIO) support for a total of eight
ports.
The PC87382 enables glueless implementation of an LPC-
to-LPC Switch between the motherboard LPC bus and the
Docking Station, and supports hot insertion and hot removal.
Outstanding Features
G
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
G
LPC bus interface, based on Intel’s
LPC Interface
