ABSOLUTE MAXIMUM RATINGS
1)
1. Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. Functional operation should be
restricted to recommended operating condition. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

TIMING WAVEFORM OF WRITE CYCLE(3)
(UB, LB Controlled)
NOTES
(WRITE CYCLE)
1. A wri
t
e occurs during the overlap(t
WP
) of low CS
1
and low WE. A write begins when CS
1
goes low and WE goes low with asserting
UB or LB for single byte operation or simultaneously asserting UB and LB for double byte operation. A write ends at the earliest tran-
sition when CS
1
goes high and WE goes high. The
t
WP
is measured from the beginning of write to the end of write.
2.
t
CW
is measured from the CS
1
going low to the end of write.
3. t
AS
is measured from the address valid to the beginning of write.
4.
t
WR
is measured from the end of write to the address change.
t
WR
applied in case a write ends as CS
