Functional overview

2.23.1

Advanced-control timers (TIM1, TIM8)

The advanced-control timers (TIM1, TIM8) can be seen as three-phase PWM generators

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

inserted dead times. They can also be considered as complete general-purpose timers.

Their 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 standard 16-bit timers, they have the same features as the general-purpose

TIMx timers. If configured as 16-bit PWM generators, they have full modulation capability (0-

100%).

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

feature for synchronization or event chaining.

TIM1 and TIM8 support independent DMA request generation.

2.23.2

General-purpose timers (TIMx)

There are ten synchronizable general-purpose timers embedded in the STM32F76xxx

devices (see Table 6 for differences).

•

TIM2, TIM3, TIM4, TIM5

The STM32F76xxx include 4 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/PWMs 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.

2.23.3

Basic timers TIM6 and TIM7

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

used as a generic 16-bit time base.

TIM6 and TIM7 support independent DMA request generation.
