1. VCC must be applied before VPP and removed after VPP.
2. VPP must not exceed 13V, including overshoot.
3. Do not change VPP from VIL to 12.5V or 12.5V to VIL when CE = low.
4. DC electrical parameters for programming operations are not tested. These parameters are guaranteed by design.
5. Device reliability may be adversely be affected if the device is installed or removed while VPP = 12.5V.
