The Low Pin Count Interface was defined by Intel
(Q470E only)
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 embed-
ded 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'. The table below indicates the
®
pin functions of the LPC connector.
