What ICs are used in this rocket?

Radiation-hardened FPGAs and microcontrollers/SoCs most likely if they are "old space".
Or they could be using consumer devices with higher tolerance to single event upsets which is the SpaceX ("new space") approach - reasonably normal computers (they use x86 Intel processors of one kind or another) but with much redundancy and self-checking.

That thread seems to imply that radiation hardened ICs and large scale redundancy are alternatives, but that's not really true. The two have usually been combined to achieve acceptable results.

So everything digital from Italy uses spaghetti logic :-//
And the USA has burger logic >:D

The OP already has a thread on hardened semiconductors, discrete vs IC etc... https://www.eevblog.com/forum/renewable-energy/discrete-smps-have-any-advantages/
Quite why he wants to know the manufacturers of the silicon in this particular rocket is beyond me. Ed: Whether they use Vicor power modules, even more so.

Sometimes it also uses structural noodles, but payload and deltaV suffers...
