PC87363
128-Pin LPC SuperI/O with MIDI and Game Ports, Extended
Wake-Up and Protection
General Description
The PC87363, a member of National Semiconductor’s 128-
pin LPC SuperI/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 compliant, and offers a single-
chip solution to the most commonly 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), Sys-
tem Wake-Up Control (SWC), General-Purpose Input/Out-
put (GPIO) support for a total of 49 ports and an enhanced
WATCHDOG™ timer.
