Here we go again with suffixed parts (STM32G474RET6U)

waclawek.jan · ‎2019-09-19

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

M suffix, the description could not be more weird, "specific supply chain"...

Even more weirdly, it *is* present as a separate part directly in the respective webfolder's "sample&buy":

Btw., what's the point of providing a "boilerplate" picture which has no material connection with the real product? (MEY is WLCSP81)? Isn't ST's web ridiculous enough with its overtly active javascriptoids?

ST, you know what would be really attractive to us? If you'd provide *real photos* of *each and every* product, as they are in real life. No kidding.

The ST page you show does not imply availability in my eyes.

Well, then you have to source it from some non-specific supply chain, I guess... ;)

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.
