General-purpose timers (TIM2, TIM3, TIM4, TIM5, TIM15, TIM16,

TIM17)

There are up to seven synchronizable general-purpose timers embedded in the

STM32G483xE devices (see Table 7 for differences). Each general-purpose timer can be

used to generate PWM outputs, or act as a simple time base.

•

TIM2, TIM3, TIM4 and TIM5

They are full-featured general-purpose timers:

–

TIM2 and TIM5 have a 32-bit auto-reload up/downcounter and 32-bit prescaler

–

TIM3 and TIM4 have 16-bit auto-reload up/downcounter and 16-bit prescaler.

These timers feature 4 independent channels for input capture/output compare, PWM

or one-pulse mode output. They can work together, or with the other general-purpose

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

The counters can be frozen in debug mode.

All have independent DMA request generation and support quadrature encoders.

•

TIM15, 16 and 17

They are general-purpose timers with mid-range features:

They have 16-bit auto-reload upcounters and 16-bit prescalers.

–

TIM15 has 2 channels and 1 complementary channel

–

TIM16 and TIM17 have 1 channel and 1 complementary channel

All channels can be used for input capture/output compare, PWM or one-pulse mode

output.

The timers can work together via the Timer Link feature for synchronization or event

chaining. The timers have independent DMA request generation.

The counters can be frozen in debug mode.

3.25.3

Basic timers (TIM6 and TIM7)

The basic timers are mainly used for DAC trigger generation. They can also be used as

generic 16-bit timebases.
