Description

TIM2, TIM3, TIM4, TIM5

STM32F100xx devices feature four synchronizable 4-channel general-purpose timers.

These timers are based on a 16-bit auto-reload up/downcounter and a 16-bit prescaler.

They feature 4 independent channels each for input capture/output compare, PWM or one-

pulse mode output. This gives up to 12 input captures/output compares/PWMs on the

largest packages.

The TIM2, TIM3, TIM4, TIM5 general-purpose timers can work together or with the TIM1

advanced-control timer via the Timer Link feature for synchronization or event chaining.

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

These timers are capable of handling quadrature (incremental) encoder signals and the

digital outputs from 1 to 3 hall-effect sensors.

Their counters can be frozen in debug mode.

TIM12, TIM13 and TIM14

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

TIM12 has two independent channels, whereas TIM13 and TIM14 feature one single

channel for input capture/output compare, PWM or one-pulse mode output.

Their counters can be frozen in debug mode.

TIM15, TIM16 and TIM17

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

TIM15 has two independent channels, whereas TIM16 and TIM17 feature one single

channel for input capture/output compare, PWM or one-pulse mode output.

The TIM15, TIM16 and TIM17 timers can work together, and TIM15 can also operate with

TIM1 via the Timer Link feature for synchronization or event chaining.

TIM15 can be synchronized with TIM16 and TIM17.

TIM15, TIM16, and TIM17 have a complementary output with dead-time generation and

independent DMA request generation

Their counters can be frozen in debug mode.

Basic timers TIM6 and TIM7

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

generic 16-bit time base.

Independent watchdog

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

clocked from an independent 40 kHz internal RC and as it operates independently from the

main clock, it can operate in Stop and Standby modes. It can be used 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. The counter

can be frozen in debug mode.
