1. The DATA FORMAT shown for each bus cycle is as follows; I/O7 - I/O0 (Hex). In word operation I/O15 - I/O8
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
4. Once a sector is in the lockdown mode, data in the protected sector cannot be changed unless the chip is reset or power
5. Either one of the Product ID Exit commands can be used.
6. If data bit D1 is “0”, block B is locked. If data bit D1 is “1”, block B can be reprogrammed.
7. The default state (after power-up) of the configuration register is “00”.
8. Bytes of data other than F0 may be used to exit the Product ID mode. However, it is recommended that F0 be used.
are don’t care. The ADDRESS FORMAT shown for each bus cycle is as follows: A11 - A0 (Hex). Address A18 through A11
are don’t care in the word mode. Address A18 through A11 and A-1 are don’t care in the byte mode.
