Greating,

Our product needs to verify digital signature so I select MC56F81768. How can I get sample code about DSASS?

In addition, Currently, I am replacing LLC and TTPPFC converter control card is ussed  MC56F81768 but I only have LLC and TTPPFC sample code of MC56F82748. How can I get LLC and TTPPFC sample code of MC56F81xxx?

Thanks.

Hi,

Pls download the DSASSUG.pdf from the link.

https://www.nxp.com/products/processors-and-microcontrollers/additional-mpu-mcus-architectures/digit...

The doc tells you how to use the signature feature and have the example. If you have issue when you call the function, pls give your issue in detail.

Regarding the project for PFC and LLC, I do not know if there is project based on MC56F81xxx, I will ask AE team and give you a response later.

Greeting,

I have downloaded to DSASSUG.pdf from that URL but I didn't find Chapter 3 DSASS example application. 

3.1 Source code
The demo application of DSASS is located at [install_path]\demo_apps\dsass.

I don't know where the path is from its description and there is no link to any installation package.

Thanks, I am going to wait for your reply regarding LLC and TTPFC sample code of MC56F81xxx.

Hi,

Yes, We have the package of TPPFC and HBLLC package for MC56F81768, pls contact local FAE or sales for the package.

Regarding the DSASS feature, I suppose that the SDK package has the example code, but I do not find the DSASS example in the ...\demo_apps directory

You can download SDK package from the link:

Hope it can help you

Greeting,

I have chosen an inappropriate DSC. The MC56F81768 didn't seem to support DSASS. I searched for the SDK and didn't find the DSASS example. So my control card wants to change to MC56F3xxxx + security IC.

Does LLC or PFC have sample code of MC56F83783 that can be downloaded?

In addition, does NXP have a recommended security IC that can support ECDSA 384? Currently, I only find TA100 IC from Microchip.

Thanks.
