NOTES:
1. In systems where CE# defines the write pulse width (within a longer WE# timing waveform), all setup, hold and
inactive WE# times should be measured relative to the CE# waveform.
2. Sampled, not 100% tested.
3. Refer to Table 4 for valid A IN and D IN for block erase, full chip erase, (multi) word/byte write or block lock-bit
configuration.
4. V PP should be held at V PPH1/2/3 until determination of block erase, full chip erase, (multi) word/byte write or
block lock-bit configuration success (SR.1/3/4/5=0).
5. See Ordering Information for device speeds (valid operational combinations).
