Notes: 1. The DATA FORMAT shown for each bus cycle is as follows; I/O7 - I/O0 (Hex). In word operation I/O15 - I/O8 are Don’t Care.
The ADDRESS FORMAT shown for each bus cycle is as follows: A11 - A0 (Hex). Address A20 through A11 are Don’t Care
in the word mode. Address A20 through A11 and A-1 are Don’t Care in the byte mode.
2. Since A11 is a Don’t Care, AAA can be replaced with 2AA.
3. SA = sector address. Any byte/word address within a sector can be used to designate the sector address (see pages 9 -12
for details).
4. Once a sector is in the lockdown mode, data in the protected sector cannot be changed unless the chip is reset or power
cycled.
5. PA is the plane address (A20 - A19).
6. Either one of the Product ID Exit commands can be used.
7. If data bit D1 is “0”, block B is locked. If data bit D1 is “1”, block B can be reprogrammed.
