Note: X Don’t Care, PA Program Address, PD Program Data, BA Any address in the Block. All values in the table are in hexadecimal.
The Command Interface only uses A–1, A0-A10 and DQ0-DQ7 to verify the commands; A11-A20, DQ8-DQ14 and DQ15 are Don’t
Care. DQ15A–1 is A–1 when BYTE is V
IL
or DQ15 when BYTE is V

Table 6. Program, Erase Times and Program, Erase Endurance Cycles
Note: 1. Typical values measured at room temperature and nominal voltages.
2. Sampled, but not 100% tested.
3. Maximum value measured at worst case conditions for both temperature and V
CC
after 100,00 program/erase cycles.
