The selection guides provided in
Final selection should be based on the timing provided in the following tables. As an example, the selection
guide suggests that 4 wait states must be used for 100 MHz operation when using Page Mode DRAM.
However, by using the information in the appropriate table, a designer may choose to evaluate whether
fewer wait states might be used by determining which timing prevents operation at 100 MHz, running the
chip at a slightly lower frequency (e.g., 95 MHz), using faster DRAM (if it becomes available), and control
factors such as capacitive and resistive load to improve overall system performance.
