Powerlib source code

alannilsson — Wed, 29 Nov 2017 18:58:12 GMT

Back in this thread, NXP announced it would publish the source code for the PowerLib required to setup the PLL correctly on the 546XX. Has that happened? Where is it at?

If NXP is unwilling/unable to provide said source code, will they provide the library in mach-o file format?

We are evaluating the 546XX for an upcoming project and the availability of either the source or a mach-o format is a deal breaker for us

Hi,

The LPC5410x power lib source has already been posted on web:

Have a great day,
Sol

That is for 541xx. Is that the same as 546xx?

Update:

Due to customer interest / need for the library, we now include the source code for the power library in the SDK. For older products (like LPC546xx) we have an application note on the product page:

https://www.nxp.com/docs/en/application-note/TN00038.zip

Please carefully review the caveats to consider when making changes as these will affect power consumption and can impact product reliability if changed from recommended values used in the library.

Hi Alan,

We don't normally publish this type of source because customers could make changes to internal device settings that could impact device characteristics, hence invalidating the datasheet information.

If you require more information due to your company's policies please contact us via your NXP sales contact (or distributor if you are not working directly with NXP) to make this request.

Regards,

Brendon
