Notes:
26.All devices can operate at clock frequencies as low as 119 MHz. 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 will output data with the output timings of that frequency range.
27.t
, t
, are specified with a load capacitance of 5 pF as in part (b) of AC Test Loads. Transition is measured
±
100 mV from steady-state voltage.
28.At any given voltage and temperature t
is less than t
and t
less than t
.
29.This part has a voltage regulator internally; t
POWER
is the time that the power needs to be supplied above V
DD
minimum initially before a read or write operation
can be initiated.
30.For D0 data signal on CY7C1526V18 device, t
SD
is 0.5 ns for 200 MHz, 250 MHz, 278 MHz and 300 MHz frequencies.
