The Low Pin Count Interface was defined by Intel
®
Corporation to facilitate the industry’s
transition towards legacy free systems. It allows the integration of low-bandwidth legacy I/O
components within the system, which are typically provided by a Super I/O controller. Fur-
thermore, 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’.
