DS14540 Rev 1

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.

3.31.2

General-purpose timers

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

The devices embed up to seven synchronizable general-purpose timers (see Table 6), 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.

The timers can work together via the Timer Link feature for synchronization or event

chaining. The timers have independent DMA request generation.

The counters can be frozen in Debug mode.

3.31.3

Basic timers (TIM6 and TIM7)

These timers are mainly used for DAC trigger generation. They can also be used as generic

16-bit timebase.

3.31.4

Low-power timers

(LPTIM1, LPTIM2)

The devices embed six low-power timers. These timers have an independent clock and are

running in Stop mode if they are clocked by LSE, LSI or an external clock. They are able to

wake up the system from Stop mode.

The low-power timer supports the following features:
