Timer feature comparison
Timers and watchdogs
The ultralow power STM32L162xD devices include seven general-purpose timers, two basic
timers, and two watchdog timers.
Table 2
General-purpose timers (TIM2, TIM3, TIM4, TIM5, TIM9, TIM10 and
TIM11)
There are seven synchronizable general-purpose timers embedded in the STM32L162xD
devices (see
TIM2, TIM3, TIM4, TIM5
TIM2, TIM3, TIM4 are based on 16-bit auto-reload up/down counter. TIM5 is based on a 32-
bit auto-reload up/down counter. They include a 16-bit prescaler. They feature four
independent channels each for input capture/output compare, PWM or one-pulse mode
output. This gives up to 16 input captures/output compares/PWMs on the largest packages.
TIM2, TIM3, TIM4, TIM5 general-purpose timers can work together or with the TIM10,
TIM11 and TIM9 general-purpose timers via the Timer Link feature for synchronization or
event chaining. Their counter can be frozen in debug mode. Any of the general-purpose
timers can be used to generate PWM outputs.
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.
