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 A19 through A11
are don’t care in the word mode. Address A19 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 13 - 14
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. Either one of the Product ID Exit commands can be used.
6. Bytes of data other than F0 may be used to exit the Product ID mode. However, it is recommended that F0 be used.
7. Any address within the user programmable register region. Address locations are shown on “Protection Register Addressing
Table” on page 12.
8. If data bit D1 is “0”, block B is locked. If data bit D1 is “1”, block B can be reprogrammed.
9. The default state (after power-up) of the configuration register is “00”.
10. When accessing the data in the CFI table, the address format is A15 - A0 (Hex) in the word mode, A14 - A0 (Hex),
and A-1 = 0 in the byte mode.
