MSP432P401R: Random Number Generator

The MSP432 has no TRNG.

Each clock cycle? No MCU can do that!

As long as you don't need cryptography grade, you should be able to use a PRNG and if don't want repeats put the last value in NVRAM to use as a seed the next time.

Thanks for a reply.

Actually, it is about signal processing, not cryptography in my case. So it should yield not just 'random data', but spectrally neutral (with constant spectral density) white noise. I think this could be implemented by getting noise from ADC's lower bits. Or, I should use other technique then.

A PRNG - like drand48 - should do fine.

Yes, my CC1312 has one. I was confused for a bit, too.

I suggest you run a test on a PC with a drand48() implementation and do an FFT to make sure it looks white. Then you can implement that code in your MSP.

I also have a couple of CC1312. And I also found this article too: www.ti.com/.../slaa338a.pdf
Looks like a compromising idea for MSP anyway.
