STM32F373xx

Functional overview

3.17.1

General-purpose timers (TIM2 to TIM5, TIM12 to TIM17, TIM19)

There are eleven synchronizable general-purpose timers embedded in the STM32F373xx

(see Table 5 for differences). Each general-purpose timer can be used to generate PWM

outputs, or act as a simple time base.

•

TIM2, 3, 4, 5 and 19

These five timers are full-featured general-purpose timers:

–

TIM2 and TIM5 have 32-bit auto-reload up/downcounters and 32-bit prescalers

–

TIM3, 4, and 19 have 16-bit auto-reload up/downcounters and 16-bit prescalers

These timers all 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.

•

TIM12, 13, 14, 15, 16, 17

These six timers general-purpose timers with mid-range features:

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

–

TIM12 has 2 channels

–

TIM13 and TIM14 have 1 channel

–

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.

3.17.2

Basic timers (TIM6, TIM7, TIM18)

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

generic 16-bit time base.
