Notes. 1. VCC must be applied simultaneously with or before VPP and removed simultaneously or after VPP.
2. The Initial Program Pulse width tolerance is 1 ms ± 5%.
3. The length of the Over-program Pulse varies from 2.85 ms to 78.95 ms, depending on the multiplication value of the iteration counter.
4. Sampled only, not 100% tested.
