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, A selects, all other addresses = X.
0
5. See Table 4 for device IDs.
6. Refer to Table 6 for valid DIN during a write operation.
7. Command writes for block erase or program are only executed when VPP = VPPH1 or VPPH2
8. To program or erase the boot block, hold RP# at VHH or WP# at VIH. See Section 3.3.
9. RP# must be at GND ± 0.2 V to meet the maximum deep power-down current specified.
10. This column does not apply to the E28F004B5 since it is a x8-only device.
