MB90246A Series
RD/WRH/WRL signal standards
(AVCC = VCC = 4.5 V to 5.5 V, AVSS = VSS = 0.0 V, TA = –30
°C to +70°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.)
m: Stands for the number of RDY wait cycles. With no wait, m is set at “0”.
*1: Use the automatic ready function when the setup time is not sufficient.
*2: If the pulse width has exceeded the maximum value, the wait period may be extended beyond the specified
number of cycles by one cycle.
*3: For tCYC (cycle time (machine cycle)), see paragraph (4), “Clock output timing.”
