Table 4 ex.
Note 1
: tACC starts from RD or CS , whichever activates last
Typically, tACC = 5 + 0.9 CEXT in ns; where CEXT (external parasitic capacitance) is in pF
Note 2
: CS ,
RD , DS , WR and R/ W rise and fall times are specified by tR and tF
Note 3
: tDF starts from RD or CS , whichever deactivates first
Note 4
: tDW ends at WR or CS , whichever deactivates first
Note 5
: tDH starts from WR or CS , whichever deactivates first
Note 6
: tWC starts from WR or CS , whichever activates last and ends at WR or CS , whichever deactivates first
