1.2.5 AC Characteristics - Write Operations
NOTES:
1. The timing characteristics for reading the status register during block erase, (page buffer) program, block lock
2. A write operation can be initiated and terminated with either CE
3. Sampled, not 100% tested.
4. Write pulse width low (t
5. Write pulse width high (t
6. V
7. Refer to Table 5 for valid address and data for block erase, (page buffer) program, block lock configuration and OTP
8. The output delay time t
9. The timing is defined from the first edge of CE
10. The timing is defined from the first edge of CE
11. STS timings depend on STS configuration.
