STM32F405RGT6 part numbering mystery U V W

Can someone please tell me what adding U or V or W to this part number means ?

As Farnell and RS stock them I do not expect it to be programmed specials.

The datasheet is of no help (that I can find). I'm hazarding a guess that it may be something as simple as specific tray sizes or something like but can find nothing firm !!!

These *are* programmed parts:

Dedicated STM32 part numbers enabled for Java

- Part numbers ending with the letter U for sampling (example: STM32F417IGT6U)

- Part numbers ending with the letter J for production (example: STM32F407IGT6J)

(this info used to be on

/external-link.jspa?url=http%3A%2F%2Fwww.stm32java.com%2F

which does not appear to work anymore)

[EDIT Feb.2018]

- it says 'STM32Java SDK is an Eclipse SDK, based on MicroEJ ®' and

apears to be still available, so maybe enquiries could go there [/EDIT]

-V - MP3 decoder

-W - MP3 codec

You have to contact ST for further details.

Many Thanks

Why they make these things so difficult to work out is beyond me.

Hi morris.alan,

You find also the definition of U & J letters in the part numbers in this presentation:

http://www.st.com/st-web-ui/static/active/en/resource/sales_and_marketing/presentation/product_presentation/stm32java_mkt_pres.pdf.

This presentation provides more details on the STM32Java solution.

The list of Java-ready STM32 MCUs is given

Thanks

In this case it is actually the V part that interests me.

Knowing now that all these versions are programmed with added functionality of some sort or other. I understand pricing of these variants should be around 20% more than the base part. It just so happens RS in the UK have stock of the V part at a stangely low price. Before I ordered this version instead of the basic part. Just needed to find out what it actually was.
