Intel® 82801E C-ICH

Advance Information Datasheet

4.0

Electrical Characteristics

Note:

This document contains information on products in the sampling and initial production phases of

development. The specifications are subject to change without notice. Verify with your local Intel

sales office that you have the latest datasheet before finalizing a design.

4.1

Absolute Maximum Ratings

Note:

A non-condensing environment is required to maintain RTC accuracy.

Warning:

Stressing the device beyond the “Absolute Maximum Ratings” may cause permanent damage.

These are stress ratings only. See Section 4.2 for the Functional Operating Range of the 82801E

C-ICH.

4.2

Functional Operating Range

All of the AC and DC Characteristics specified in this document assume that the 82801E C-ICH

component is operating within the Functional Operating Range given in this section. Operation

outside of the Functional Operating Range is not recommended, and extended exposure outside of

the Functional Operating Range may affect component reliability.
