S32K1xx CMP in VLPS

fan1234 — Tue, 02 Dec 2025 09:14:55 GMT

Hello:

for s32k1xx series, is the continuous mode of CMP supported in VLPS? I want to confirm this because in section "Module operation in available power modes", it's described that "Windowed, sampled & filtered modes of operation are not available while in stop or VLPS modes."

Best regards!

Hello @fan1234,

There is Round-robin sampling mode operational in VLPS.

Here is an bare-metal example:

Thank you for the reply. i know the trigger mode is available in VLPS mode. or i should ask this --can any functional mode be used in VLPS ?

Hi @fan1234,

Where exactly do you see the statement “Windowed, sampled & filtered modes of operation are not available while in STOP or VLPS modes” in the section “Module Operation in Available Power Modes”?
Which revision of the S32K1xx Reference Manual are you using?

I don’t see any restriction regarding CMP Continuous mode in VLPS.
However, let me verify that to be certain.

Regards,

Daniel
