Here we go again with suffixed parts (STM32G474RET6U)

[waclawek.jan]

From the 'G4 DISCO UM2577:

This board features a specific STM32 device version, which allows the operation of any bundled commercial

stack/library available. This STM32 device shows a "U" marking option at the end of the standard part number

and is not available for sales.

In order to use the same commercial stack in his application, a developer may need to purchase a part number

specific to this stack/library. The price of those part numbers includes the stack/library royalties.

I can find no mention of the U suffix on the 'G474 product folder webpage, nor in the DS.

ST, can you please properly document it this time?

Thanks,

JW

B suffix in STM32F100 means "die optimized as 'F100 rather than remarked 'F103; with some minor changes" https://community.st.com/s/question/0D53W00000vOnVNSA0/dear-supportplease-help-to-check-and-advise-if-the-part-number-below-can-be-interchangeablethe-suffix-b-denotes-as-internal-code-can-i-use-stm32f100r8t6b-as-a-replacement-to-stm32f100r8t6stm32f100r8t6-stm32f100r8t6b

N suffix in some 'G0 means different pinout (presumably USB-C PD-optimized) than the "GP" (presumably General Purpose) variant.

D suffix in 'L0 meaning "BOR disabled".

(specifically in 'L05x and 'L07x) 

S suffix in 'L031 in QFN28 means "different pinout from the non-S suffix", but it also means "the same pinout as 'L011 and 'F031 in QFN28". Nice.
