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 sys
