Product Brief

February 2006

Revision 1.2

PC87382

LPC-to-LPC Switch for Docking Stations, with Fast

Infrared Port, Serial Port and GPIOs

General Description

Outstanding Features

The PC87382, a member of the Winbond LPC SuperI/O fam-

ily, is targeted for a wide range of portable applications. The

PC87382 is PC2001 and ACPI compliant, and features an

LPC-to-LPC Switch with hot plugability, Fast Infrared port

(FIR, IrDA 1.1 compliant), Serial Port, and General-Purpose

Input/Output (GPIO) support for a total of eight ports.

■ 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

■ LPC bus interface, based on Intel’s LPC Interface

Specification Revision 1.1, August 2002 (supports

CLKRUN signal)

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.

■ Fast Infrared port

■ PC2001 and ACPI Revision 3.0 compliant

■ Serial IRQ support (15 options)

■ Protection features, including GPIO lock and pin con-

figuration lock

■ Eight GPIO ports including five with “assert IRQ” capa-

bility

■ XOR Tree and TRI-STATE^device pins (for ICT) test-

ability modes.

■ 5V tolerant and back-drive protected pins (except LPC

bus pins)

■ 48-pin LQFP package
