MB90246A Series
(3) Bus Read Timing
(AVCC = VCC = 2.7 V to 5.5 V, AVSS = VSS = 0.0 V, TA = –40
°C to +85°C)
N: Stands for the number of wait cycles. With no wait, N is set at “0”. (The number of wait cycles depends on an
automatic wait and external RDY.)
* : For tCYC (cycle time (machine cycle)), see paragraph (4), “Clock output timing.”
