ELECTRICAL SPECIFICATIONS
The AC and DC specifications for the LPC interface signals (LA0[3:0], LFRAME, LCLCK and RST#) are defined in Sec-
tion 4.2.2.4 of the PCI local bus specification, Rev. 2.1. Refer to Table 14 for the DC voltage and current specifications.
Refer to Tables 18 through 24 for the AC timing specifications for Clock, Read, Write, and Reset operations.
Absolute Maximum Stress Ratings
(Applied conditions greater than those listed under “Absolute Maximum
Stress Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation
of the device at these conditions or conditions greater than those defined in the operational sections of this data
sheet is not implied. Exposure to absolute maximum stress rating conditions may affect device reliability.)
