Description
28/170
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 TIM1 and TIM8 counters can be frozen in debug mode. Many of the advanced-control
timer features are shared with those of the standard TIMx timers which have the same
architecture. The advanced-control timer can therefore work together with the TIMx timers
via the Timer Link feature for synchronization or event chaining.
General-purpose timers (TIMx)
There are ten synchronizable general-purpose timers embedded in the STM32F20x devices
(see

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.
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
TIM2, TIM3, TIM4, TIM5
The STM32F20x include 4 full-featured general-purpose timers. TIM2 and TIM5 are
32-bit timers, and TIM3 and TIM4 are 16-bit timers. 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.
The counters of TIM2, TIM3, TIM4, TIM5 can be frozen in debug mode. 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.
TIM10, TIM11 and TIM9
These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler.
TIM10 and TIM11 feature one independent channel, whereas TIM9 has 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.
TIM12, TIM13 and TIM14
These timers are based on a 16-bit auto-reload upcounter and a 16-bit prescaler.
TIM13 and TIM14 feature one independent channel, whereas TIM12 has 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.
