Chapter 5
The Low Pin Count Interface was defined by Intel
tion towards legacy free systems. It allows the integration of low-bandwidth legacy I/O compo-
nents within the system, which are typically provided by a Super I/O controller. Furthermore, it
can be used to interface firmware hubs, Trusted Platform Module (TPM) devices and embedded
controllers. Data transfer on the LPC bus is implemented over a 4 bit serialized data interface,
which uses a 24MHz LPC bus clock. For more information about LPC bus, please refer to the
Intel
Low Pin Count Interface Specification Revision 1.1'. The table below indicates the pin as-
®
signments of the LPC connector.
