COMMUNICATION INTERFACE CHARACTERISTICS (Cont’d)
13.11.3 I
1) The device must internally provide a hold time of at least 300 ns for the SDA signal in order to bridge
2) The maximum hold time of the START condition has only to be met if the interface does not stretch the
Cb = total capacitance of one bus line in pF
146/161
Bus free time between a STOP and START con-
dition
Hold time START condition. After this period,
LOW period of the SCL clock
HIGH period of the SCL clock
Set-up time for a repeated START condition
Data hold time
Data set-up time
Rise time of both SDA and SCL signals
Fall time of both SDA and SCL signals
Set-up time for STOP condition
