Notes

23.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.

24.This part has a voltage regulator internally; tPOWER is the time that the power must be supplied above VDD minimum initially before a read or write operation can be initiated.

25.For D2 data signal on CY7C1426BV18 device, tSD is 0.5 ns for 200 MHz, 250 MHz, 278 MHz and 300 MHz frequencies.
