Note: Values in this data sheet are design goals and are subject to change based on the results of device characterization.
15.1 Absolute Maximum Ratings
Caution! The absolute maximum ratings in Table 21 indicate levels where permanent damage to the device can occur, even if these
limits are exceeded for only a brief duration. Functional operation is not guaranteed under these conditions. Excluding VBAT,
operation at the absolute maximum conditions for extended periods can adversely affect long-term reliability of the device.

1. Functionality is guaranteed, but specifications require derating at extreme temperatures (see the specification tables for details).
15.3 Electrostatic Discharge Specifications
Extreme caution must be exercised to prevent electrostatic discharge (ESD) damage. Proper use of wrist and heel grounding straps
to discharge static electricity is required when handling these devices. Always store unused material in its antistatic packaging.
