It appears that STM32F205RCT6 is out of stock everywhere. The problem seems world wide for many ICs as it reported in https://www.eevblog.com/forum/microcont ... ilability/ , https://www.reddit.com/r/embedded/comme ... _of_stock/ and other places.
I have just a few ICs left so there will be delays for new orders until the stock re-appears.
