6.3.18 TIM timer characteristics
The parameters given in Table 57 are guaranteed by design.
Refer to Section 6.3.16: I/O port characteristics for details on the input/output alternate
function characteristics (output compare, input capture, external clock, PWM output).
6.3.19 Communications interfaces
I
2
C interface characteristics
The I
2
C interface meets the requirements of the standard I
2
C 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 V
DD
is
disabled, but is still present.
The I
2
C characteristics are described in Table 58. Refer also to Section 6.3.16: I/O port
characteristics
for more details on the input/output alternate function characteristics (SDA
and SCL)
.
The I
2
C bus interface supports standard mode (up to 100 kHz) and fast mode (up to 400
kHz). The I
2
C bus frequency can be increased up to 1 MHz. For more details about the
complete solution, please contact your local ST sales representative.
Table 57. TIMx characteristics
(1)(2)
1. TIMx is used as a general term to refer to the TIM1 to TIM11 timers.
2. Guaranteed by design.
Symbol Parameter

(3)
3. The maximum timer frequency on APB1 is 50 MHz and on APB2 is up to 100 MHz, by setting the TIMPRE
bit in the RCC_DCKCFGR register, if APBx prescaler is 1 or 2 or 4, then TIMxCLK = HCKL, otherwise
TIMxCLK >= 4x PCLKx.
