Since some months, everyone can buy a board with this IC.
It is compatible with the ATMega328 and has some features like 12bit ADC (instead of 10 bit), DAC, unique ID and also 32MHz.
But I can't find it in the "normal" shops. Also on the LCSC it is not available. Only in this shop:
https://www.electrodragon.com/product/5pcs-logicgreen-lgt8f328p/
For 0.68$ compared to the 2$ for the atmega326P-AU of the other electronic parts shops (it is cheaper than the cheapest attiny with ADC!)
So the question. Is this chip just a clone for private use or can it be used as official alternative to the more expensive and original ATMega328?
