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 !!!- Mark as New

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]https://web.archive.org/web/20160304025323/http://www.stm32java.com/
- 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. JW- Mark as New

Why they make these things so difficult to work out is beyond me.- Mark as New

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.
