Notes: 1. Transition is measured ±200 mV from steady voltage with output load (B). This parameter is
sampled and not 100% tested.
2. Address should be valid prior to or coincident with CS# transition low.
3. WE# and/or CS# must be high during address transition time.
4. If CS# and OE# are low during this period, I/O pins are in the output state. Then, the data input
signals of opposite phase to the outputs must not be applied to them.
5. If the CS# low transition occurs simultaneously with the WE# low transition or after the WE#
transition, output remains a high impedance state.
6. tAS is measured from the latest address transition to the later of CS# or WE# going low.
7. tWR is measured from the earlier of CS# or WE# going high to the first address transition.
8. A write occurs during the overlap of a low CS# and a low WE#. A write begins at the latest
transition among CS# going low and WE# going low. A write ends at the earliest transition
among CS# going high and WE# going high. tWP is measured from the beginning of write to the
end of write.
9. tCW is measured from the later of CS# going low to the end of write.
