Communications interfaces
I
2C interface characteristics
Unless otherwise specified, the parameters given in Table 50 are derived from tests
performed under ambient temperature, fPCLK1 frequency and VDD supply voltage conditions
summarized in Table 10.
The STM32F103xC performance line 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 50. Refer also to Section 5.3.13: I/O port
characteristics for more details on the input/output alternate function characteristics (SDA
and SCL).
Table 50.

Parameter
Standard mode I2C(1)
1.
Guaranteed by design, not tested in production.
Fast mode I2C(1)(2)
2.
fPCLK1 must be higher than 2 MHz to achieve the maximum standard mode I
2C frequency. It must be
higher than 4 MHz to achieve the maximum fast mode I2C frequency.

The maximum hold time of the Start condition has only to be met if the interface does not stretch the low
period of SCL signal.

4.
The device must internally provide a hold time of at least 300ns for the SDA signal in order to bridge the
undefined region of the falling edge of SCL.
