LPC connector
The Low Pin Count Interface was defi ned by Intel
dustry'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. Furthermore, it can be used to interface fi rmware hubs,
Trusted Platform Module (TPM) devices 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 Specifi cation Revision 1.1'.
