I2C - inter IC control interface
Subject to general operating conditions for V33, fPCLK1, and TA unless otherwise specified.
The STR7 I2C interface meets the requirements of the Standard I2C communications
protocol described in the following table with the restriction mentioned below:
Note:
Restriction: The I/O pins which SDA and SCL are mapped to are not “True” Open-Drain:
when configured as open-drain, the PMOS connected between the I/O pin and V33 is
disabled, but it is still present. Also, there is a protection diode between the I/O pin and V33.
Consequently, when using this I2C in a multi-master network, it is not possible to power off
the STR7X while some another I2C master node remains powered on: otherwise, the
STR7X will be powered by the protection diode.
Refer to I/O port characteristics for more details on the input/output alternate function
characteristics (SDA and SCL).
