Notes:
1. Not 100% tested.
2. See the “Erase and Programming Performance” section for more information.
3. For 1–16 words/1–32 bytes programmed.
4. Effective write buffer specification is based upon a 16-word/32-byte write buffer operation.
5. Unless otherwise indicated, AC specifications for 80 ns and 90 ns speed options are tested with V = V = 3 V.
