(VDDi = 1.3V± 0.05V (400MHz), VDDi = 1.3 V± 0.05V (266MHz), T
Parameter
LR Clock Input Delay
Serial Data Setup Time
Serial Data Hold Time
(VDDi = 1.3V± 0.05V (400MHz), VDDi = 1.3 V± 0.05V (266MHz), TA = -40 to 85°C, VDD_OP2 = 3.3V ± 0.3V)
Parameter
SCL clock frequency
SCL high level pulse width
SCL low level pulse width
Bus free time between STOP and START
START hold time
SDA hold time
SDA setup time
STOP setup time
NOTES: Std. means Standard Mode and fast means Fast Mode.
1. The IIC data hold time(tSDAH) is minimum 0ns.
(IIC data hold time is minimum 0ns for standard/fast bus mode in IIC specification v2.1.)
Please check the data hold time of your IIC device if it's 0 nS or not.
2. The IIC controller supports only IIC bus device(standard/fast bus mode), not C bus device.
