PC87364 Datasheet | National Semiconductor

Description The PC87364, a member of National Semiconductor’s 128pin LPC Super I/O family, introduces wake-up support for a wide range of wake-up events, and new hardware and sofware 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 pliant, and offers a single-chip solution to the most monly 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.
