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).

1. TIMx is used as a general term to refer to the TIM1, TIM2, TIM3, TIM4, TIM15, TIM16 and TIM17 timers.

2. CHx is used as a general term to refer to CH1 to CH4 for TIM1, TIM2, TIM3 and TIM4, to the CH1 to CH2

for TIM15, and to CH1 for TIM16 and TIM17.

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).
