Notes:
1. Not 100% tested.
2. See the “Erase and Programming Performance” section for
more information.
6. AC Specifications listed are tested with VIO = VCC. Contact
AMD for information on AC operation with VIO ≠ VCC
.
3. For 1–16 words/1–32 bytes programmed.
7. When using the program suspend/resume feature, if the
suspend command is issued within tPOLL, tPOLL must be fully
re-applied upon resuming the programming operation. If the
suspend command is issued after tPOLL, tPOLL is not
required again prior to reading the status bits upon
resuming.
4. Effective write buffer specification is based upon a
16-word/32-byte write buffer operation.
5. Word/Byte programming specification is based upon a
single word/byte programming operation not utilizing the
write buffer.
