6.3 Timing Nomenclature

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:

tCE

tELQV time(t) from CEX# (E) going low (L) to the outputs (Q) becoming valid (V)

tOE

tGLQV time(t) from OE # (G) going low (L) to the outputs (Q) becoming valid (V)

tACC

tAVQV time(t) from address (A) valid (V) to the outputs (Q) becoming valid (V)

tAS

tAVWH time(t) from address (A) valid (V) to WE# (W) going high (H)

tDH

tWHDX time(t) from WE# (W) going high (H) to when the data (D) can become undefined (X)
