82801DBM ICH4-M Datasheet
Note: A non-condensing environment is required to maintain RTC accuracy.
This chapter provides the absolute maximum ratings, DC characteristics, AC characteristics, and
AC timing diagrams.
Absolute Maximum Ratings
Stressing the device beyond the “Absolute Maximum Ratings” may cause permanent damage.
These are stress ratings only. See
Functional Operating Range
All of the AC and DC Characteristics specified in this document assume that the ICH4 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.
