NOTES:
1. Refer to DC Characteristics.
2. X can be VIL, VIH for control pins and addresses, VPPLK or VPPH for VPP.
3. See DC Characteristics for VPPLK, VPPH1, VPPH2, VHH, VID voltages.
4. Manufacturer and device codes may also be accessed via a CUI write sequence, A1–A17 = X, A1–A18 = X.
5. See Table 5 for device IDs.
6. Refer to Table 7 for valid DIN during a write operation.
7. Command writes for block erase or word/byte program are only executed when VPP = VPPH1 or VPPH2.
8. To write or erase the boot block, hold RP# at VHH or WP# at VIH. See Section 3.4.
9. RP# must be at GND ± 0.2V to meet the maximum deep power-down current specified.
