Notes: 1. VCC must be applied simultaneously or before VPP and removed simultaneously or after VPP.

2. VPP must not exceed 13 V including overshoot.

3. An influence may be had upon device reliability if the device is installed or removed while VPP =

12.5 V.

4. Do not alter VPP either VIL to 12.5 V or 12.5 V to VIL when CE = low.

5. VIL min = –0.6 V for pulse width ≤ 20 ns.

6. If VIH is over the specified maximum value, programming operation cannot be guaranteed.
