Shaded area contains preliminary information.
Notes:
4.
Test conditions assume signal transition times of 5 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V, and output loading of the specified
I
/I
and 30-pF load capacitance.
At any given temperature and voltage condition, t
is less than t
for any given device. These parameters are guaranteed by design and not 100% tested.
t
and t
are specified with C
= 5 pF as in part (b) of AC Test Loads and Waveforms. Transition is measured
±
500 mV from steady-state voltage.
The internal write time of the memory is defined by the overlap of CS LOW and WE LOW. Both signals must be LOW to initiate a write and either signal can
terminate a write by going HIGH. The data input set-up and hold timing should be referenced to the rising edge of the signal that terminates the write.
