The Intel(R) 8 Series/C220 Series Desktop Super SKU LPC Controller - 8C42 is a component of Intel’s 8 Series/C220 Series Chipset for desktop systems. It is a part of the Low Pin Count (LPC) interface that facilitates communication between the motherboard's chipset and various peripheral devices. Specifically, the LPC Controller (8C42) is responsible for controlling legacy I/O devices, such as system boards, parallel ports, and other low-speed devices that still rely on the LPC bus for communication.

This device may show up in Device Manager under the System Devices section and is often associated with the proper operation of your motherboard’s chipset. If you're experiencing issues or the driver is missing, you will need to install the Intel Chipset Driver package, which includes the appropriate driver for the LPC Controller (8C42).
