NOTES:
1. Write is defined as either any SBx and SW low or SGW is low. Chip Enable is defined as SE1 low, SE2 high, and SE3 low whenever ADSP
or ADSC is asserted.
2. All read and write cycle timings are referenced from K or G.
3. G is a don’t care after write cycle begins. To prevent bus contention, G should be negated prior to start of write cycle.
4. In order to reduce test correlation issues and to reduce the effects of application specific input edge rate variations on correlation between
data sheet parameters and actual system performance, FSRAM AC parametric specifications are always specified at VDDQ/2. In some
design exercises, it is desirable to evaluate timing using other reference levels. Since the maximum test input edge rate is known and is given
in the AC Test Conditions section of the data sheet as 1 V/ns, one can easily interpolate timing values to other reference levels.
5. This parameter is sampled and not 100% tested.
6. Measured at
±
200 mV from steady state.
