Communications interfaces
I
2C interface characteristics
Unless otherwise specified, the parameters given in Table 47 are derived from tests
performed under the ambient temperature, fPCLK1 frequency and VDD supply voltage
conditions summarized in Table 10.
The STM32F20x and STM32F205xx I
2C interface meets the requirements of the standard
I
2C communication protocol with the following restrictions: the I/O pins 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 VDD is disabled, but is still present.
The I
2C characteristics are described in Table 47. Refer also to Section 5.3.16: I/O port
characteristics for more details on the input/output alternate function characteristics (SDA
and SCL).
