*1) This Timing assumes a load capacitance of 50pF.

*2) In the above table, the parenthesized specifications apply when VCC=3.3±0.3V. Accordingly, the non-parenthesized specifications alone apply

whether VCC=5V±10% or 3.3±0.3V.

NOTE

Setup time of data to falling edge of CIOWR# (tdsu) depends on setup time of address to IOW# of system (Stdsu).

tdsu (min.)=Stdsu-30ns.m
