Note:
*1. Ts
= System clock period
*2. t4min
= 2Ts + 5
*3. t11max = 1Ts + 7 (for 5.0V)
*4. t12min = 1Ts (for a read cycle followed by a read or write cycle)
= 2Ts + 2 (for a write cycle followed by a write cycle)
= 5Ts + 2 (for a write cycle followed by a read cycle)
*5. t13max = 4Ts + 2
*6. Input signal rise/fall time should be less than 4.5ns
*7. for details, please see the S1D13709 data sheet
