102 / 177 page  Electrical characteristics STM32F20xxx 102/177 Doc ID 15818 Rev 9 5.3.19 Communications interfaces I 2C interface characteristics Unless otherwise specified, the parameters given in Table 50 are derived from tests performed under the ambient temperature, fPCLK1 frequency and VDD supply voltage conditions summarized in Table 12. STM32F205xx and STM32F207xx I 2C 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 I 2C characteristics are described in Table 50. Refer also to Section 5.3.16: I/O port characteristics for more details on the input/output alternate function characteristics (SDA and SCL). Table 49. Characteristics of TIMx connected to the APB2 domain(1) 1. TIMx is used as a general term to refer to the TIM1, TIM8, TIM9, TIM10, and TIM11 timers.
