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 being 

operated and outputs data with the output timings of that frequency range.

22. This part has a voltage regulator internally; t

POWER

 is the time that the power must be supplied above V

DD

 minimum initially before a read or write operation can be 

initiated.

23. For D2 data signal on CY7C1992CV18 device, t

SD

 is 0.5 ns for 200 MHz, 250 MHz, 278 MHz, and 300 MHz frequencies.
