PC87363 Datasheet | National Semiconductor

Description The PC87363, a member of National Semiconductor’s 128pin LPC Super I/O family, introduces a Musical Instrument Digital Interface (MIDI) Port and Game Port inputs for up to two game devices. It also offers wake-up support for a wide range of wake-up events, and new hardware and software features to protect the system design. Like all members of this family, it is PC99 and ACPI pliant, and offers a singlechip solution to the most monly used PC I/O peripherals. The PC87363 also incorporates: Fan Speed Control and Monitoring for two 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, ACCESS.bus® Interface (ACB), System Wake-Up Control (SWC), General-Purpose Input/Output (GPIO) support for a total of 49 ports and an enhanced WATCHDOG™ timer.
