NOTES:
1.
Read timing characteristics during block erase, program, and lock-bit configuration operations are the same as during
read-only operations. Refer to AC Characteristics
—Read-Only Operations
.
A write operation can be initiated and terminated with either CE# or WE#.
Sampled, not 100% tested.
Refer to Table 3 for valid A
IN
and D
IN
for block erase, program, or lock-bit configuration.
V
should be held at V
(and if necessary RP# should be held at V
HH
) until determination of block erase, program, or
lock-bit configuration success (SR.1/3/4/5 = 0).
See
Ordering Information
for device speeds (valid operational combinations).
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
= t
= t
= t
WLEH
= t
ELWH
. If CE# is driven low 10 ns before WE# going low,
WE# pulse width requirement decreases to t
WP
- 20 ns.
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 last). Hence, t
WPH
= t
WHWL
= t
EHEL
= t
WHEL
= t
