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.

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