Table B Characteristics of the SDA and SCL bus lines for I
SDA
SCL
Bus free time between a STOP and START condition
Hold time (repeated) START condition. After this period,
the first clock pulse is generated
LOW period of the SCL clock
Set-up time for a repeated START condition
Fall time of both SDA and SCL signals
Set-up time for STOP condition
Capacitive load for each bus line
SCL clock fequency
HIGH period of the SCL clock
Data hold time
Data set-up time
Rise time of both SDA and SCL signals
All values referred to V
∗ A device must internally provide a hold time of at least 300ns for the SDA signal (referred to the V
in order to bridge the undefined region of the falling edge of SCL.
