1. These parameters depend on the cycle rate and are measured with the cycle determined by the minimum value of t
CK
and t
RC
.
Input signals are changed up to three times during t
RC
(min).
2. The specified values are obtained with the output open.
3. Input signals are changed once during t
CK
(min).
4. Input signals are changed once during three clock cycles.
5. Active Standby Current will be higher if Clock Suspend is entered during a burst read cycle (add 1mA per DQ).
6. Input signals are stable.
7. SP: Standard power; LP: Low power.
