Hello, I'm hoping someone can help me identify a few smd components. I've been doing a lot of googling with no luck. These are on a board that controls a couple of small 24VDC solenoid-operated pneumatic valves based on inputs from a couple of sensors.
Thanks in advance for your help!

I googled "phf6 qfn", got a picture of very similar chip but S103. Then googled stm8s003 datasheet, and on page 96/103 is UFQFPN20 package with marking S033 in the top row.
If you google S033 qfn you will get even better result for pictures.
