NOTES:
1. Read timing characteristics during write and erase operations are the same as during read-only operations. Refer to AC
Characteristics during Read Mode.
2. The on-chip WSM completely automates program/erase operations; program/erase algorithms are now controlled inter-
nally which includes verify and margining operations.
3. Refer to command definition table for valid A
IN
.
4. Refer to command definition table for valid D
IN
.
5. Program/Erase durations are measured to valid SRD data (successful operation, SR.7
e
1).
6. For Boot Block Program/Erase, PWD
Y
should be held at V
HH
until operation completes successfully.
7. Time t
PHBR
is required for successful relocking of the Boot Block.
8. Sampled but not 100% tested.
