NOTES:

1. See DC Characteristics for VIL or VIH voltages.

2. X can be VIL or VIH.

3. RST# at GND±0.2V ensures the lowest power consumption.

4. Command writes involving block erase, full chip erase, (page buffer) program or OTP program are reliably

executed when VCC=2.7V-3.6V.

5. Refer to Table 6 for valid DIN during a write operation.

6. Never hold OE# low and WE# low at the same timing.

7. Refer to Appendix of LH28F320BF series for more information about query code.

8. RY/BY# is VOL when the WSM (Write State Machine) is executing internal block erase, full chip erase,

(page buffer) program or OTP program algorithms. It is High Z during when the WSM is not busy, in

block erase suspend mode (with program and page buffer program inactive), (page buffer) program suspend

mode, or reset mode.
