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.

Thermal Characteristics
The ICH is designed for operation at case temperatures between 0°C and 100°C.

D.C. Characteristics
NOTES:
1. Icc(RTC) data is taken with Vcc(RTC) at 3.0V while the system is in a mechanical off (G3) state at room
temperature. As Vcc(RTC) drops the current will also drop. At 2.5V the typical Icc(RTC) is 1.4uA.
