I've been using STM32F405R processors on my boards for a while. I once figured out what the numbers and letters after the R mean, but they were not of any importance to me. (I have plenty with 512Mb flash).
This time when ordering a new batch of '405 processors, they (farnell) are offering the STM32F405RGT6V and the "V" here was new to me. So I looked things up in the datasheet. There it says something like: "xxx" packaging options like TR for tape and reel.
I would like to be sure that it doesn't mean something like "cheaper version without the second and third ADC".
