Notes
1. VDD must be applied before VPP and removed after VPP.
2. VPP must not exceed 14 V including overshoot.
3. The device reliability can be affected when the device is installed or removed while VPP =12V.
4. Do not alter VPP either ‘VIL to 12 V’ or ‘12 V to VIL’ when CE = VIL.
5. VIL(min) = 0.5 V for pulse width < 20 ns.
6. If VIH is over the specified maximum value, programming operation cannot be guaranteed.
Table 28 AC characteristics during command programming, data programming and erase operation
Tamb = 0 to 70 °C; VDD =5V+ 10%; VPP = 12 V + 5%; refer to Figs 23 to 27.
