Electrical Characteristics
This chapter contains the absolute maximum operating ratings, power characteristics, and DC
characteristics for the 845MP/845MZ MCH-M.
6.1.
Absolute Maximum Ratings
Table 34 lists the Intel 845MP/845MZ Chipset MCH-M maximum environmental stress ratings.
Functional operation at the absolute maximum and minimum is neither implied nor guaranteed.
Functional operating parameters are listed in the AC and DC tables.
Warning: Stressing the device beyond the “Absolute Maximum Ratings” may cause permanent damage. These are
stress ratings only. Operating beyond the “operating conditions” is not recommended and extended
exposure beyond “operating conditions” may affect reliability.
