STM32F413xG/H

Functional overview

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

output. This gives up to 15 input capture/output compare/PWMs

TIM2. TIM3, TIM4 and TIM5 general-purpose timers can operate together or in

conjunction with the other general-purpose timers and TIM1 advanced-control timer via

the Timer Link feature for synchronization or event chaining.

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

TIM2. TIM3, TIM4 and TIM5 channels 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 TIM2. TIM3, TIM4 and TIM5 full-

featured general-purpose timers or used as simple time bases.

3.22.3

Basic timer (TIM6, TIM7)

TIM6 and TIM7 timers are basic 16-bit timers. They support independent DMA request

generation.

3.22.4

Low-power timer (LPTIM1)

The low-power timer (LPTIM1) features an independent clock and runs in Stop mode if it is

clocked by LSE, LSI or by an external clock. LPTIM1 is able to wakeup the devices from

Stop mode.

The low-power timer main features are the following:

•

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

–

Internal clock source: LSE, LSI, HSI or APB1 clock

–

External clock source over LPTIM1 input (working even with no internal clock

source running, used by the pulse counter application)

•

Programmable digital glitch filter

•

Encoder mode

•

Active in Stop mode.

3.22.5

Independent watchdog

The independent watchdog is based on a 12-bit downcounter and 8-bit prescaler. It is

clocked from an independent 32 kHz internal RC and as it operates independently from the

main clock, it can operate in Stop and Standby modes. It can be used either as a watchdog

to reset the device when a problem occurs, or as a free-running timer for application timeout

management. It is hardware- or software-configurable through the option bytes.
