Hi,
PN7150 supports Mifare plus, but there is no example for this topic, you have to develop it by yourself, but as you mentioned, you want to use PN7150 with a bare metal MCU, so why not select NFC frontend like CLRC663 plus? The NFC reader library for RC663 contain the demo for Mifare plus. Please refer to the following for details.

You may request it from the docstore. Please refer to the attached guide for more details.
Have a great day,
Kan
