Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V.
At any given temperature and voltage condition, t
t
This parameter is guaranteed by design and is not tested.
The internal Write time of the memory is defined by the overlap of CE LOW, WE LOW and BHE/BLE LOW. CE, WE and BHE/BLE must be LOW to initiate a Write,
and the transition of these signals can terminate the Write. The input data set-up and hold timing should be referenced to the leading edge of the signal that terminates the Write.
