AC Characteristics—Write Operations, continued
NOTES:
1. Refer to command definition table (
Table 6
) for valid A
or D
.
2. 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
= t
. Similarly, 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
= t
WHWL
= t
EHEL
= t
WHEL
= t
EHWL
.
3. Sampled, but not 100% tested.
Read timing characteristics during program suspend and erase suspend are the same as during read-only
operations.
See
Figure 5
for timing measurements and maximum allowable input slew rate.
See
Figure 8, “AC Waveform: Program and Erase Operations” on page 32
