l The input signal rise time and fall time (tr, tf) is specified at 15 ns or less. When the system cycle time is extremely fast,
(tr + tf) ⤠(tCYC8 â tCCLW â tCCHW) is specified.
l All timing is specified using 20% and 80% of VDD1 as the reference.
l tCCLW is specified as the overlap between CSB being âLâ and /WR being at the âLâ level.
