NOTES:

CEX low is defined as the first edge of CE0, CE1, or CE2 that enables the device. CEX high is defined at the first edge of CE0, CE1,

or CE2 that disables the device (see Table 13).

1. Read timing characteristics during block erase, program, and lock-bit configuration operations are the same as

during read-only operations. Refer to AC Characteristics–Read-Only Operations.

2. A write operation can be initiated and terminated with either CEX or WE#.

3. Sampled, not 100% tested.

4. Write pulse width (tWP) is defined from CEX or WE# going low (whichever goes low last) to CEX or WE# going

high (whichever goes high first). Hence, tWP = tWLWH = tELEH = tWLEH = tELWH.

5. Refer to Table 14 for valid AIN and DIN for block erase, program, or lock-bit configuration.

6. Write pulse width high (tWPH) is defined from CEX or WE# going high (whichever goes high first) to CEX or WE#

going low (whichever goes low first). Hence, tWPH = tWHWL = tEHEL = tWHEL = tEHWL.

7. For array access, tAVQV is required in addition to tWHGL for any accesses after a write.

8. STS timings are based on STS configured in its RY/BY# default mode.

9. VPEN should be held at VPENH until determination of block erase, program, or lock-bit configuration success

(SR[1,3,4:5] = 0).
