Revision 1.0
PC87384
Legacy-Reduced SuperI/O with Serial Port, Parallel Port
and GPIOs for Notebook and Docking Applications
General Description
Outstanding Features
The PC87384, a member of the Winbond LPC SuperI/O
family, is targeted for a wide range of notebook and docking
applications where an FIR port is not required. The
PC87384 is PC2001 and ACPI compliant, and features Se-
rial Port, Parallel Port and General-Purpose Input/Output
(GPIO) support for a total of 21 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 3.0 compliant
■ Serial IRQ support (15 options)
■ Protection features, including GPIO lock and pin con-
figuration lock
■ 21 GPIO ports, including 14 with “assert IRQ” capability
■ XOR Tree and TRI-STATE device pins (for ICT) test-
ability modes.
■ 5V tolerant and back-drive protected pins (except LPC
bus pins)
■ 64-pin TQFP package
