(7) Normal Bus Access and Read/Write Operations
(VCC
= 3.15 V to 3.6 V, VSS = AVSS = 0 V, TA = 0 °C to +70 °C)
*1 : If the bus is extended with either automatic wait insertion or RDY input, add the (tCYC
× the number of extended
cycles) time to this value.
*2 : This is the value at the time of (gear cycle
× 1) .
When the gear cycle is set to 1/2, 1/4 or 1/8, substitute “n” in the following formula with 1/2, 1/4 or 1/8 respectively.
Formula : (2
− n / 2) × tCYC − 40
