6 / 18 page AT49BV1604(T)/1614(T) 6 Notes: 1. The DATA FORMAT in each bus cycle is as follows: I/O15 - I/O8 (Don’t Care); I/O7 - I/O0 (Hex). The ADDRESS FORMAT in each bus cycle is as follows: A15 - A0 (Hex), A-1, A14 - A19 (Don’t Care). 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 pages for details). 4. When the sector programming lockout feature is not enabled, the sector will erase (from the same sector erase command). Once the sector has been protected, data in the protected sectors cannot be changed unless the RESET pin is taken to 12V ± 0.5V. 5. PA is the plane address (A19 - A18).

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.
