NOTES:
1. Refer to DC Characteristics. When VPP ≤ VPPLK, memory contents can be read, but not altered.
2. X can be VIL or VIH for control and address input pins and VPPLK or VPPH1/2/3 for VPP. See DC Characteristics for VPPLK and
VPPH1/2/3 voltages.
3. RY/BY# is VOL when the WSM is executing internal block erase, program, or lock-bit configuration algorithms. It is VOH
when the WSM is not busy, in block erase suspend mode (with program inactive), program suspend mode, or deep power-
down mode.
4. RP# at GND ± 0.2 V ensures the lowest deep power-down current.
5. See Section 4.2 for read identifier code data.
6. Command writes involving block erase, write, or lock-bit configuration are reliably executed when VPP = VPPH1/2/3 and
VCC = VCC2/3 (see Section 6.2 for operating conditions).
7. Refer to Table 4 for valid DIN during a write operation.
