5.4 I2C Bus Timing Specification
PARAMETER
SYMBOL
SCL clock frequency
Hold time (repeated) START condition.
After this period, the first clock pulse is generated.
Low period of the SCL clock
HIGH period of the SCL clock
Set-up time for a repeated START condition
Data hold time. For I2C-bus device
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
Bus free time between a STOP and START
Capacitive load for each bus line
Noise margin at the LOW level for each connected
device (including hysteresis)
Noise margin at the HIGH level for each
connected device (including hysteresis)
Note1: It depends on the "high" period time of SCL.
