Hi,

I'm a bit confused due to package for STM32F051K4U6. I'm going to use it in our product, and already ordered few from

http://eu.mouser.com/ProductDetail/STMicroelectronics/STM32F051K4U6/?qs=sGAEpiMZZMt4jl5TkKljYKMYADYcslqm

.However, according to product info it has

UFQFN-48

package. I checked datasheet, and there is no such package described. What datasheet I have to refer? Does it have same pin naming as LQFP48? BTW will this product be supported for few years? #package #support

DigiKey says it's a 32UFQFN which is more consistent with ST's documentation

STM32F1 parts have been around since 2006, I'd suspect this to be a reasonably good runner. If you buy millions of them, it shouldn't be an issue. Most parts EOL because of volume or process issues.
