NOTES:
1. Refer to DC Characteristics. When V
2. X can be V
3. RST# at GND±0.2V ensures the lowest power consumption.
4. Command writes involving block erase, (page buffer) program or OTP program are reliably executed when
5. Refer to Table 6 for valid D
6. Never hold OE# low and WE# low at the same timing.
7. Refer to Appendix of LH28F640BF series for more information about query code.
