LPC stand for Low Pin Count - it is the chip used to connect all of the "legacy" PC components on motherboards. For example it will control the PS/2, floppy, parallel and serial ports.

Before the LPC all of these devices were in the ISA bus and once boards stopped including them ISA slots, they switched to LPC because it was a simplifier interface for the small number of integrated devices they required. It is named becaue it has a lower pin count than ISA.
