SEE NEW DESIGN RECOMMENDATIONS
All 3.3V system timings are measured from where signals cross 1.5V.
For 5.0V systems use the standard JEDEC cross point definitions.
Each timing parameter consists of 5 characters. Some common examples are defined below:
t
CE
t
ELQV
time(t) from CE
X
# (E) going low (L) to the outputs (Q) becoming valid (V)
t
OE
t
GLQV
time(t) from OE # (G) going low (L) to the outputs (Q) becoming valid (V)
t
ACC
t
AVQV
time(t) from address (A) valid (V) to the outputs (Q) becoming valid (V)
t
AS
t
AVWH
time(t) from address (A) valid (V) to WE# (W) going high (H)
t
DH
t
WHDX
time(t) from WE# (W) going high (H) to when the data (D) can become undefined (X)
