AC CHARACTERISTICS
SRAM Write Cycle
Notes:
1. WE# controlled, if CIOs is low, ignore UB#s and LB#s timing.
2. t
CW
is measured from CE1#s going low to the end of write.
3. t
WR
is measured from the end of write to the address change. t
WR
applied in case a write ends as CE1#s or WE# going high.
4. t
AS
is measured from the address valid to the beginning of write.
5. A write occurs during the overlap (t
WP
) of low CE#1 and low WE#. A write begins when CE1#s goes low and WE# goes low when
asserting UB#s or LB#s for a single byte operation or simultaneously asserting UB#s and LB#s for a double byte operation. A
write ends at the earliest transition when CE1#s goes high and WE# goes high. The t
WP
is measured from the beginning of write
to the end of write.
