STM32 devices names end with: VGTx, VGHx, RETx, REYx.The first 2 seem to be associated with memory size and the last 2 to the package. Is there any logic to it and is there any document describing it?

Hi all,
we are working on our second custom boardfor our product, using STM32F446RET6 MCU, 8MHz HSE and 746Hz LSE external crystals. From the first board to this one the only difference it's that all needed chip...

I'm trying to implement an asynchronous USART using ISR to communicate with FTDI and Bluetooth Modules (RX and TX at 115kbps). I have a STM32F446RE with the following test code:

I noticed some problems with the RTC value after waking up from an interrupt (_WFI() instruction) so I made this code to test it out. It prints RTC value in seconds since the epoch and sleeps after 5s:

I have a custom board with STM32F446RE, with RTC powered by coin cell batteries. After testing 2 boards in the field for several days they stoped working and, while debugging, I realised that there a timeout in...
