SRAM AC Characteristics—Write Operations
(1, 2)
NOTES:
1. See
Figure 10, “AC Waveform: SRAM Write Operations” on page 31
.
2. A write occurs during the overlap (t
WP
) of low S-CS
1
# and low S-WE#. A write begins when S-CS
1
# goes low
and S-WE# goes low with asserting S-UB# or S-LB# for single byte operation or simultaneously asserting
S-UB# and S-LB# for double byte operation. A write ends at the earliest transition when S-CS
1
# goes high
and S-WE# goes high. The t
WP
is measured from the beginning of write to the end of write.
3. t
WP
is measured from S-CS
1
# going low to end of write.
4. t
AS
is measured from the address valid to the beginning of write.
5. t
WR
is measured from the end of write to the address change. t
WR
applied in case a write ends as S-CS
1
# or
S-WE# going high.
