DS11854 Rev 6

The advanced-control timer can work together with the TIMx timers via the timer Link

feature for synchronization or event chaining.

The TIM1 and TIM8 support independent DMA request generation.

3.20.2

General-purpose timers (TIMx)

There are ten synchronizable general-purpose timers embedded in the STM32F732xx and

STM32F733xx devices (see Table 6 for differences).

•

TIM2, TIM3, TIM4, TIM5

The STM32F732xx and STM32F733xx include four full-featured general-purpose

timers: TIM2, TIM5, TIM3, and TIM4.The TIM2 and TIM5 timers are based on a 32-bit

auto-reload up/downcounter and a 16-bit prescaler. The TIM3 and TIM4 timers are

based on a 16-bit auto-reload up/downcounter and a 16-bit prescaler. They all feature 4

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

output. This gives up to 16 input capture/output compare/PWM on the largest

packages.

The TIM2, TIM3, TIM4, TIM5 general-purpose timers can work together, or with the

other general-purpose timers and the advanced-control timers TIM1 and TIM8 via the

timer link feature for synchronization or event chaining.

Any of these general-purpose timers can be used to generate PWM outputs.

TIM2, TIM3, TIM4, TIM5 all have independent DMA request generation. They are

capable of handling quadrature (incremental) encoder signals and the digital outputs

from 1 to 4 hall-effect sensors.

•

TIM9, TIM10, TIM11, TIM12, TIM13, and TIM14

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

TIM10, TIM11, TIM13, and TIM14 feature one independent channel, whereas TIM9

and TIM12 have 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.

3.20.3

Basic timers TIM6 and TIM7

These timers are mainly used for the DAC trigger and waveform generation. They can also

be used as a generic 16-bit time base.

The TIM6 and TIM7 support independent DMA request generation.

3.20.4

Low-power timer (LPTIM1)

The low-power timer has an independent clock and is running also in Stop mode if it is

clocked by LSE, LSI or an external clock. It is able to wakeup the devices from Stop mode.

This low-power timer supports the following features:

•

16-bit up counter with 16-bit autoreload register

•

16-bit compare register

•

configurable output: pulse, PWM

•

continuous/one-shot mode

•

selectable software/hardware input trigger

•

selectable clock source:
