Inter IC control interface (I2C)
Subject to general operating conditions for V
The STM8TL53C4/G4 I2C interface meets the requirements of the Standard I
communication protocol described in the following table with the restrictions mentioned
below.
Refer to I/O port characteristics for more details on the input/output alternate function
characteristics (SDA and SCL).

2. Data based on standard I
3. The maximum hold time of the START condition has only to be met if the interface does not stretch the
4. The device must internally provide a hold time of at least 300 ns for the SDA signal in order to bridge the
For speeds around 200 kHz, achieved speed can have
For other speed ranges, achieved speed can have
The above variations depend on the accuracy of the external components used.
