To our customers,
Old Company Name in Catalogs and Other Documents
On April 1st, 2010, NEC Electronics Corporation merged with Renesas Technology
Corporation, and Renesas Electronics Corporation took over all the business of both
companies. Therefore, although the old company name remains in this document, it is a valid
Renesas Electronics document. We appreciate your understanding.

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.
