NOTES:
1. The timing characteristics for reading the status register during block erase, full chip erase, 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 (t WP ) 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, t WP =t WLWH =t ELEH =t WLEH =t ELWH .
5. Write pulse width high (t WPH ) 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, t WPH =t WHWL =t EHEL =t WHEL =t EHWL .
6. t WHR0 (t EHR0 ) after the Read Query or Read Identifier Codes/OTP command=t AVQV +100ns.
7. Refer to Table 4 for valid address and data for block erase, full chip erase, program, OTP program or lock bit
configuration.
