5.2 Comparator (COMP)

MSPM0 and NXP's M0 MCUs both offer integrated comparators as optional peripherals on some devices. In the MSPM0 family, comparators are denoted as COMPx, where the 'x' final character refers to the specific comparator module being considered. The S32K1xx family features a COMP module with an internal single comparator with six to eight inputs, the KEA128x family supports up to four inputs, and the KM35x Up to six inputs. The MSPM0 comparator module provides a windowed comparator functionality using its DAC with two programmable levels. Both MSPM0 and NXP's M0 MCUs have multiple channels that can take inputs from various internal and external sources and can be used to trigger changes in power mode or truncate/control PWM signals. A summary of how the MSPM0 and NXP M0 comparator modules compare feature-by-feature is included in Table 5-3.
