Ultralow power comparators
The high density STM8L162xx devices embed two comparators (COMP1 and COMP2)
sharing the same current bias and voltage reference. The voltage reference can be internal
or external (coming from an I/O).
●
●
The two comparators can be used together to offer a window function. They can wake up
from Halt mode.
12-bit analog-to-digital converter (ADC1) with 28 channels (including 4 fast channel),
temperature sensor and internal reference voltage
Conversion time down to 1 µs with f
Programmable resolution
Programmable sampling time
Single and continuous mode of conversion
Scan capability: automatic conversion performed on a selected group of analog inputs
Analog watchdog: interrupt generation when the converted voltage is outside the
programmed threshold
Triggered by timer
12-bit DAC with 2 buffered outputs (two digital signals can be converted into two analog
voltage signal outputs)
Synchronized update capability using timers
DMA capability for each channel
External triggers for conversion
Noise-wave generation
Triangular-wave generation
Dual DAC channels with independent or simultaneous conversions
Input reference voltage V
One comparator with fixed threshold (COMP1).
One comparator rail to rail with fast or slow mode (COMP2). The threshold can be one
of the following:
