PC87364
128-Pin LPC SuperI/O with Extended Wake-Up and
Protection Support
General Description
The PC87364, a member of National Semiconductor’s 128-
pin LPC SuperI/O family, introduces wake-up support for a
wide range of wake-up events, and new hardware and sof-
ware features to protect the system design. The PC87364
provides support for 51 GPIO ports, many with Assert
IRQ/SMI/PWUREQ capability. It is PC99 and ACPI compli-
ant, and offers a single-chip solution to the most commonly
used PC I/O peripherals.
The PC87364 also incorporates: Fan Speed Control and
Monitor (FSCM) for three fans, a Floppy Disk Controller
(FDC), a Keyboard and Mouse Controller (KBC), a full IEEE
1284 Parallel Port, two enhanced Serial Ports (UARTs), one
with Infrared (IR) support, an ACCESS.bus® Interface
(ACB), System Wake-Up Control (SWC), General-Purpose
Input/Output (GPIO) support for 51 ports, Interrupt Serializer
for Parallel IRQs and an enhanced WATCHDOG™ timer.
Outstanding Features
• Extended Wake-Up support, including legacy/ACPI
power button support, direct power supply control in
response to wake-up events, power-fail recovery
• Protection features, including I/O access lock, chassis
hood lock/unlock, chassis intrusion detection, GPIO pin
attribute lock and pin configuration lock
• Fan Speed Control and Monitor for three fans
• Serial IRQ support (15 options)
• Interrupt Serializer (11 Parallel IRQs to Serial IRQ)
• Bus interface, based on Intel’s LPC Interface Specifi-
cation Revision 1.0, September 29th, 1997
• ACCESS.bus Interface, SMBus physical layer compatible
q 51 GPIO Ports (39 standard, including 23 with Assert
IRQ/SMI/PWUREQs interrupts; 12 VSB-powered)
• Blinking LEDs
• 128-pin PQFP Package
