Data Sheet

Microchip Technology Company

Electrical Specifications

The AC and DC specifications for the LPC interface signals (LAD[3:0], LFRAME#, LCLCK and RST#) as

defined in Section 4.2.2.4 of the PCI local Bus specification, Rev. 2.1. Refer to Table 22 for the DC voltage and

current specifications. Refer to Table 26 through Table 28 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 con-

ditions may affect device reliability.)
