NOTES:
1. Measured at
±
200 mV from steady state.
2. In no case may control input signals (e.g., SS) be operated with pulse widths less than the minimum clock input pulse width specifications
(e.g., tKHKL) or at frequencies that exceed the applied K clock frequency.
3. Tested per AC Test Load diagram. See Figure 1.
The table of timing values shows either a minimum or a
maximum limit for each parameter. Input requirements are
specified from the external system point of view. Thus, ad-
dress setup time is shown as a minimum since the system
must supply at least that much time. On the other hand, re-
sponses from the memory are specified from the device
point of view. Thus, the access time is shown as a maximum
since the device never provides data later than that time.
