VREFH range in MCX-C24x

Jiri_n — Sat, 07 Mar 2026 10:32:52 GMT

I would like to use an external VREFH reference voltage, however the MCX-C24x datasheet does not contain the VREFH acceptable voltage range. Interesting that KL27, MCX-C04x or MCX-C44x datasheets declare the VREFH range as 1.13V up to VDDA, but C24x one is missing it. (rev4/2025)

Is it safe to assume the C24x is the same case and range 1.17V - VDDA can be applied?

Thanks

Hello @Jiri_n

Thanks for your reply. I will confirm this internally and get back to you as soon as possible. I apologize for the inconvenience caused.

Hi @Jiri_n

Thanks for your patience.

After confirming internally, we can use the reference voltage range of the MCXC44X for the MCXC24X.

Thank you.
