NOTES:
1. The timing characteristics for reading the status register during block erase, full chip erase, (page buffer) program and
OTP program operations are the same as during read-only operations. Refer to AC Characteristics for read-only
operations.
2. A write operation can be initiated and terminated with either CE# or WE#.
3. Sampled, not 100% tested.
4. Write pulse width (tWP) is defined from the falling edge of CE# or WE# (whichever goes low last) to the rising edge of
CE# or WE# (whichever goes high first). Hence, tWP=tWLWH=tELEH=tWLEH=tELWH.
5. Write pulse width high (tWPH) is defined from the rising edge of CE# or WE# (whichever goes high first) to the falling
edge of CE# or WE# (whichever goes low last). Hence, tWPH=tWHWL=tEHEL=tWHEL=tEHWL.
6. VPP should be held at VPP=VPPH1/2 until determination of block erase, full chip erase, (page buffer) program or OTP
program success (SR.1/3/4/5=0).
7. tWHR0 (tEHR0) after the Read Query or Read Identifier Codes/OTP command=tAVQV+100ns.
8. Refer to Table 6 for valid address and data for block erase, full chip erase, (page buffer) program, OTP program or lock bit
configuration.
