TIMx characteristics

The parameters given in Table 47 are guaranteed by design.

Refer to Section 5.3.13: I/O current injection 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, TIM5, TIM15, TIM16 and TIM17

timers.

2. CHx is used as a general term to refer to CH1 to CH4 for TIM1, TIM2, TIM3, TIM4 and TIM5, 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 48 are preliminary values derived

from tests performed under the ambient temperature, fPCLK1 frequency and VDD supply

voltage conditions summarized in Table 9.

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 48. Refer also to Section 5.3.13: I/O current

injection characteristics for more details on the input/output alternate function characteristics

(SDA and SCL).
