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.
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 10 and
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. PA is the plane address (A19-A18).
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.
AT49BV1604A(T)/1614A(T)
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.

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.
