Table 7. Read and Standby Modes AC Characteristics
Note: 1. The maximum value of this timing is applicable if E1 is kept Low with addresses unchanged.If needed by the system operation,
please contact your local ST representative for relaxation of the 1000ns limitation.
2. Addresses should not be changed during t
AVAX
(min).
3. These parameters are measured according to the conditions on input and output timing reference voltage shown on
Figure 6., AC
Measurement I/O Waveform
.
4. The output load capacitance is 5pF without any other load.
5. These timings are given for E1 Low.
6. t
AVAX
(min) must be satisfied.
7. If the current value of t
WHGL
is lower than the minimum value given in the above table, t
AVQV
during the following Read operation
may increase by t
