PARAMETER (1) | MIN | MAX | UNIT |
---|
fclock | Clock frequency, IICx_SCL (2) (50% reference points) | Full speed | | 400 | kHz |
Standard mode | | 100 | kHz |
CL | Capacitive Load (for each bus line) | Capacitive Load (for each bus line) | | 200 | pF |
(1) Meets all I2C timing per the I2C Bus Specification (except for capacitive loading as specified). For reference, see Version 2.1 of the Phillips-NXP specification.
(2) By definition, I2C transactions operate at the speed of the slowest device on the bus. Full Speed operation requires all other I2C devices on the bus to support Full Speed operation. The length of the line (due to its capacitance), as well as the value of the I2C pullup resistors, can reduce the obtainable clock rate.
