1Stresses above those listed under Absolute Maximum Ratings may cause
permanent damage to the device. This is a stress rating only; functional
operation of the device at these or any other conditions above those listed in
the operational sections of this specification is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device
reliability.
2AGND and DGND are shorted internally on the ADuC844.
3Applies to P1.2 to P1.7 pins operating in analog or digital input modes.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V
readily accumulate on the human body and test equipment and can discharge without
detection. Although the ADuC844 features proprietary ESD protection circuitry,
permanent damage may occur on devices subjected to high-energy electrostatic
discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
