1. The DATA FORMAT in each bus cycle is as follows: I/O15 - I/O8 (Don’t Care); I/O7 - I/O0 (Hex).
2. Either one of the Product ID Exit commands can be used.
3. SA = sector address. Any byte/word address within a sector can be used to designate the sector address (see next two
4. When the sector programming lockout feature is not enabled, the sector will erase (from the same Sector Erase command).
5. PA is the plane address (A19 - A18).
The ADDRESS FORMAT in each bus cycle is as follows: A15 - A0 (Hex). Address A19 through A14 are don’t care in the
word mode. Address A19 through A14 and A-1 are don’t care in the byte mode.

Once the sector has been protected, data in the protected sectors cannot be changed unless the RESET pin is taken to
12V ± 0.5V.

Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or any
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect device
reliability.
