*Stresses greater than those listed under "Absolute Maximum
Ratings" may cause permanent damage to the device. This is
a stress rating only and functional operation of the device at
these or any other conditions above those indicated in the
operation section of this specification is not implied.
Exposure to absolute maximum rating conditions for extended
periods may affect reliability.
** All voltage values are with respect to GND.

NOTES:
1. V_CC must be applied before or at the same time as V_PP and removed after or at the same time as V_PP. The deivce must not be inserted into or removed from the
board when V_PP or V_CC is applied.
2. V_PP can be connected to V_CC directly (except in the program mode). V_CC supply current in this case would be I_CC + I_PP. During programming, V_PP must be
maintained at 13V ± 0.25V.
