TIMx characteristics
The parameters given in Table 37 are guaranteed by design.
Refer to Section 5.3.12: I/O port characteristics for details on the input/output alternate
function characteristics (output compare, input capture, external clock, PWM output).
5.3.15
Communications interfaces
I2C interface characteristics
Unless otherwise specified, the parameters given in Table 38 are derived from tests
performed under the ambient temperature, fPCLK1 frequency and VDD supply voltage
conditions summarized in Table 8.
The STM32F100xx value line I2C interface meets the requirements of the standard I2C
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 I2C characteristics are described in Table 38. Refer also to Section 5.3.12: I/O port
characteristics for more details on the input/output alternate function characteristics (SDA
and SCL).
