Notes
21. When a part with a maximum frequency above 167 MHz is operating at a lower clock frequency, it requires the input timings of the frequency range in which it is operated
and outputs data with the output timings of that frequency range.
22.This part has an internal voltage regulator; t
POWER
is the time that the power is supplied above V
DD
min initially before a read or write operation can be initiated.
