STM32G4xx process technology (nm)

Hello,I would like to know the process size used in the STM32G4xx. I understand the 'F4, L4 and G0 are 90 nm and the 'H7 is 40nm. My interest stems from an application in a high RF environment, where larger process size would seem to be more robust...

Resolved! Failing to receive data on MCU set up as SPI slave

Trying to receive data on MCU (L432KC) configured as SPI slave. I have tried using interrupt and DMA, but no luck. I have set up the circuit like this : 1 MCU acts as master sending 1,2,3 every 500ms interval (I hooked up master lines to scope and th...
