Ultralow power comparators and reference voltage
The STM32L15xxx embeds two comparators sharing the same current bias and reference
voltage. The reference voltage can be internal or external (coming from an I/O).
●
one comparator with fixed threshold
●
one comparator with rail-to-rail inputs, fast or slow mode. The threshold can be one of
the following:
–
DAC output
–
External I/O
–
Internal reference voltage (VREFINT) or VREFINT submultiple (1/4, 1/2, 3/4)
Both comparators can wake up from Stop mode, and be combined into a window
comparator.
The internal reference voltage is available externally via a low power / low current output
buffer (driving current capability of 1 A typical).
3.13
Routing interface
This interface controls the internal routing of I/Os to TIM2, TIM3, TIM4 and to the
comparator and reference voltage output.
3.14
Timers and watchdogs
The ultralow power STM32L15xxx devices include six general-purpose timers, two basic
timers and two watchdog timers.
Table 3 compares the features of the general-purpose and basic timers.
3.14.1
General-purpose timers (TIM2, TIM3, TIM4, TIM9, TIM10 and TIM11)
There are six synchronizable general-purpose timers embedded in the STM32L15xxx
devices (see Table 3 for differences).
