STM32L151x6/8/B, STM32L152x6/8/B

Functional overview

46

This dual digital Interface supports the following features:

•

two DAC converters: one for each output channel

•

left or right data alignment in 12-bit mode

•

synchronized update capability

•

noise-wave generation

•

triangular-wave generation

•

dual DAC channels’ independent or simultaneous conversions

•

DMA capability for each channel (including the underrun interrupt)

•

external triggers for conversion

•

input reference voltage V

REF+

Eight DAC trigger inputs are used in the STM32L15xx6/8/B. The DAC channels are
triggered through the timer update outputs that are also connected to different DMA
channels.

3.12

Ultralow power comparators and reference voltage

The STM32L15xx6/8/B 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 (V

REFINT

) or V

REFINT

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 µA 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 Touch

sensing

The STM32L15xx6/8/B devices provide a simple solution for adding capacitive sensing
functionality to any application. These devices offer up to 20 capacitive sensing channels
distributed over 10 analog I/O groups. Only software capacitive sensing acquisition mode is
supported.

Capacitive sensing technology is able to detect the presence of a finger near a sensor which
is protected from direct touch by a dielectric (glass, plastic, ...). The capacitive variation
introduced by the finger (or any conductive object) is measured using a proven
implementation based on a surface charge transfer acquisition principle. It consists of
