LPC55S36 User Manual

BrKu — Tue, 23 Sep 2025 20:45:33 GMT

Where can I find the user manual for the LPC553xx / LPC55S3xx? The user manual on the product page is the eval board user manual. Specifically, I'm looking for information on how to read the on-board temperature sensor as in UM11126 section 39.7.6

Thanks

Thanks, Alice.

Section 47.3.7 in the document you provided describes to how to set the ADC up to gather the temperature sensor data, and the equation to convert that data into a temperature, but not the coefficients for the equation. It does state:

A, B, and α are specified constant values from the ADC electrical information in the chip data sheet

I haven't been able to find them in either of the data sheets listed on the product page:
https://www.nxp.com/docs/en/data-sheet/LPC55S3xDS.pdf

https://www.nxp.com/docs/en/data-sheet/LPC553x.pdf

(But it wouldn't be the first time I missed a needle in a haystack). Where can I find them?

Thanks

Hi @BrKu

Thanks for your reply.

I will confirm with our internal team and create a private ticket for you to follow up.
Regarding the values A, B, and α, please also refer to the SDK demo lpadc_temperature_measurement.
