Enhanced Super I/O Controller with LPC Interface
Datasheet
6
The LPC47M112 is a 3.3 Volt part. It is intended solely for 3.3V applications. Non-LPC bus pins are 5V tolerant; that
is, the input voltage is 5.5V max, and the I/O buffer output pads are backdrive protected.
The LPC interface pins are 3.3 Volt only. These signals meet PCI DC specifications for 3.3V signaling. These pins
are:
The input voltage for all other pins is 5.5V max. These pins include all non-LPC Bus pins and the following pins:
