I would like to know the S912XEQ512F1MAG and MC9S12XEQ512MAG component on the body of the printing What is the difference.
Agents tell me that the S912XEQ512F1MAG is an automotive-grade device, and the MC9S12XEQ512MAG is an industrial grade, and the two pieces of material are printed on the same body. I would like how the different device printing the same, I received the goods after the goods how to determine the goods I need the model.

The S912XEQ512F1MAG and MC9S12XEQ512MAG are the same S12XE MCU derivatives.
The MC9S12XEQ512MAG is Generic / mask-independent part number. It means that you typically get the latest available version of this chip. But you may sometimes get also older version – per current availability.
On another side, the S912XEQ512F1MAG is Maskset specific part number where F1 specifies mask version and production fab. In this case, the MCU is produced in ATMC fab and maskset is 1M12S.
Both MCUs are automotive qualified, but maskset specific part is one of the typical requirements for automotive industry – therefore automotive customers prefer MCUs with maskset specific part numbers.
Note: next option is J3 which refers to TSMC FAB3 and maskset 3M25J.
Note: The maskset is typically also printed directly on MCU package.
Note: The next typical requirements for the automotive industry is production in two locations for avoiding delivery issues caused for example by natural disaster or quality incident.
Note: Since 3M25J and 1M12S masksets are practically functionally identical, you may order S912XEQ512BMAG device where a chip with 3M25J or 1M12S maskset will be assembled but you will never get older or newer version of these masks.
Note: S912XEQ512Axxx refers to 2M25J and 0M12S masksets.
I hope it helps you.
Have a great day,
Radek
