3.33.1

Advanced-control timers (TIM1, TIM8)

These timers can be seen as a three-phase PWM multiplexed on six channels. They have

complementary PWM outputs with programmable inserted dead-times. They can also be

seen as complete general-purpose timers.

The four independent channels can be used for:

•

Input capture

•

Output compare

•

PWM generation (edge or center-aligned modes) with full modulation capability

(0 - 100 %)

•

One-pulse mode output

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

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

Many features are shared with the general-purpose TIMx timers (described in the next

section) using the same architecture, so the advanced-control timers can work together with

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

3.33.2

General-purpose timers

(TIM2, TIM3, TIM4, TIM5, TIM12, TIM15)

The devices embed up to seven synchronizable general-purpose timers (see Table 7), each

of them can be used to generate PWM outputs, or act as a simple time base.

•

TIM2 and TIM5

Full-featured general-purpose timers with 32-bit auto-reload up/downcounter and 32-bit

prescaler.

These timers feature four independent channels for input capture/output compare,

PWM or one-pulse mode output. They can work together, or with the other general-

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

The counters can be frozen in Debug mode.

All have independent DMA request generation and support quadrature encoders.

•

TIM3 and TIM4

Full-featured general-purpose timers with 16-bit auto-reload up/downcounter and 16-bit

prescaler.

These timers feature four independent channels for input capture/output compare,

PWM or one-pulse mode output.

They can work together, or with the other general-purpose timers via the Timer Link

feature for synchronization or event chaining.

The counters can be frozen in Debug mode. All have independent DMA request

generation and support quadrature encoders.

•

TIM12, and 15

General-purpose timers with mid-range features.

They have 16-bit auto-reload upcounters and 16-bit prescalers.

–

TIM12 and TIM15 have two channels and one complementary channel

All channels can be used for input capture/output compare, PWM or one-pulse mode

output.
