NOTES:
1. Read timing characteristics during program and erase operations are the same as during read-only operations. Refer to AC
Characteristics
—Read-Only Operations.
2. The on-chip WSM completely automates program/erase operations; program/erase algorithms are now controlled internally
which includes verify operations.
3. Refer to command definition table for valid A
IN
. (Table 7)
4. Refer to command definition table for valid D
IN
. (Table 7)
5. Program/erase durations are measured to valid SRD data (successful operation, SR.7 = 1).
6. For boot block program/erase, RP# should be held at V
HH
or WP# should be held at V
IH
until operation completes
successfully.
7. Time t
PHBR
is required for successful locking of the boot block.
8. Sampled, but not 100% tested.
9. Write pulse width (t
) is defined from CE# or WE# going low (whichever goes low last)
to CE# or WE# going high
(whichever goes high first). Hence, t
WP

WLWH

ELEH

10. Write pulse width high (t
) is defined from CE# or WE# going high (whichever goes high first)
to CE# or WE# going low
(whichever goes low first). Hence, t
WPH
