Maybe I ask a simple question about what the meaning of stm32's model name

like 'stm32f407vgt6', what's the 'v', 'g', 't', '6' mean? 

or f407 I know '4' is about cortex-m4, but 07 means something special?

Thanks a lot

I usually use look  into data sheet:

see figure 5.

I think 07 in this case is a device type - no general rule

As Bogdan replied, the appended letter/number combination designates the Flash/RAM size, package, and temperature range variant.

For the 'F407' - and the rest (STM32), this is just a brand name 'owned' by ST.

Just like with numbers in car model names.

Does anybody know what the number 911 in 'Porsche 911' is supposed to mean ?

One can see some patterns here - see at the columns - R for 64-pin, V for 100-pin, etc. Rows also seem to have meaning for this F1 line.

I use CubeMX when it comes to device selection - you can easily select what you need and the app gives you the results according to selected criteria:
