Revision 1.0  
PC87381  
Legacy-Reduced SuperI/O with Fast Infrared Port,  
Serial Port and GPIOs  
General Description  
Outstanding Features  
The PC87381, a member of the National Semiconductor  
LPC SuperI/O family, is targeted for legacy-reduced ultra-  
light portable applications. The PC87381 is PC2001 and  
ACPI compliant, and features a Fast Infrared port (FIR, IrDA  
1.1 compliant), Serial Port and General-Purpose Input/Out-  
put (GPIO) support for a total of 11 ports.  
LPC bus interface, based on Intel’s LPC Interface  
Specification Revision 1.1, August 2002 (supports  
CLKRUN and LPCPD signals)  
PC2001 and ACPI Revision 2.0 compliant  
Fast Infrared port  
Serial IRQ support  
The PC87381 minimizes the number of legacy devices on  
the motherboard, thus taking another step towards a legacy-  
free PC.  
Protection features, including GPIO lock and pin con-  
figuration lock  
11 GPIO ports, including six with “assert IRQ” capability  
Two testability modes (XOR Tree and TRI-STATE  
pins)  
5V tolerant and back-drive protected pins (except LPC  
bus pins)  
48-pin LQFP package
