What is the LPC Interface Controller Windows Driver?

The LPC Interface Controller (Low Pin Count Interface) driver is a system driver that allows communication between the motherboard's LPC bus and other components of the computer. It typically supports hardware such as embedded controllers (which handle tasks like power management, thermal management, etc.) and legacy I/O devices (such as serial ports or parallel ports).

The LPC bus is a legacy bus interface that was commonly used for communication between the CPU and peripheral devices in older systems. While modern systems often use newer buses (like PCI Express), the LPC bus is still used in some systems to connect certain low-bandwidth devices like embedded controllers or low-power management chips.

The LPC Interface Controller driver ensures that the operating system can communicate properly with these hardware components and manage the functions they perform.
