1. The DATA FORMAT in each bus cycle is as follows: I/O15 - I/O8 (Don’t Care); I/O7 - I/O0 (Hex)
2. The boot sector has the address range 00000H to 03FFFH for the AT49F004; 7C000H to 7FFFFH for the AT49F004T;
3. Either one of the Product ID Exit commands can be used.
4. SA = sector addresses: (A18 - A0)
The ADDRESS FORMAT in each bus cycle is as follows: A15 - A0 (Hex), A-1, and A15 - A18 (Don’t Care)
00000H to 01FFFH for the AT49F4096A; and 3E000H to 3FFFFH for the AT49F4096AT.

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.
