Hello, I've outsourced a design based on a STPM33. I've thought the freelancer did a great job during the design phase but the prototypes production were a big failure. Since I've received the boards, I've lost confidence in his skills. I've checked ...

Hi,I'm working on a design with a STPM33. The application only needs to measure current on a single phase but, as STPM33 seems cheaper than STPM32, this was the chosen IC. Could I remove C27 and C28 if the second channel is not used? If yes, could I...

Hi,I have a STPM33 on some of my PCB and I have issue with some of them when it gets too hot. The actual datasheet tells us that the operating temperature range is -40C to +105C but I've found an old one of October 2013, another of October 2014, anot...

Thanks for your answer. We're still actively using STPM33 so yes, it's useful to know.

I solved the issue. It appears that the more the STPM33 gets hot, the more it's sensible to SPI timings. I adapted my device driver with better timings for read/write operations on registers and I have no more issues on old and newer boards with thes...
