Advanced-control timers (TIM1 and TIM8)

The two advanced-control timers (TIM1 and TIM8) can each be seen as a three-phase

PWM multiplexed on 6 channels. They have complementary PWM outputs with

programmable inserted dead-times. They can also be seen as a complete general-purpose

timer. The 4 independent channels can be used for:

●

Input capture

●

Output compare

●

PWM generation (edge or center-aligned modes)

●

One-pulse mode output

If configured as a standard 16-bit timer, it has the same features as the TIMx timer. If

configured as the 16-bit PWM generator, it has full modulation capability (0-100%).

In debug mode, the advanced-control timer counter can be frozen and the PWM outputs

disabled to turn off any power switch driven by these outputs.

Many features are shared with those of the general-purpose TIM timers which have the

same architecture. The advanced-control timer can therefore work together with the TIM

timers via the Timer Link feature for synchronization or event chaining.

General-purpose timers (TIMx)

There are10 synchronizable general-purpose timers embedded in the STM32F103xF and

STM32F103xG performance line devices (see Table 4 for differences).

●

TIM2, TIM3, TIM4, TIM5

There are up to 4 synchronizable general-purpose timers (TIM2, TIM3, TIM4 and TIM5)

embedded in the STM32F103xF and STM32F103xG access line devices.

These timers are based on a 16-bit auto-reload up/down counter, a 16-bit prescaler

and feature 4 independent channels each for input capture/output compare, PWM or

one-pulse mode output. This gives up to 16 input captures / output compares / PWMs

on the largest packages.

Their counter can be frozen in debug mode. Any of the general-purpose timers can be

used to generate PWM outputs. They all have independent DMA request generation.

These timers are capable of handling quadrature (incremental) encoder signals and the

digital outputs from 1 to 3 hall-effect sensors.

●

TIM10, TIM11 and TIM9

These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler.

TIM10 and TIM11 feature one independent channel, whereas TIM9 has two

independent channels for input capture/output compare, PWM or one-pulse mode

output. They can be synchronized with the TIM2, TIM3, TIM4, TIM5 full-featured

general-purpose timers. They can also be used as simple time bases.

●

TIM13, TIM14 and TIM12

These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler.

TIM13 and TIM14 feature one independent channel, whereas TIM12 has two

independent channels for input capture/output compare, PWM or one-pulse mode

output. They can be synchronized with the TIM2, TIM3, TIM4, TIM5 full-featured

general-purpose timers. They can also be used as simple time bases.
