The Low Pin Count Interface was defined by Intel
®
Corporation to facilitate the industry’s tran
-
sition towards legacy free systems. It allows the integration of low-bandwidth legacy I/O com-
ponents within the system, which are typically provided by a Super I/O controller. Furthermore,
it can be used to interface firmware hubs, and embedded controller solutions. Data transfer on
the LPC bus is implemented over a 4 bit serialized data interface, which uses a 33MHz LPC
bus clock. For more information about LPC bus refer to the Intel
®
Low Pin Count Interface
Specification Revision 1.1’.
