Resolved! Understanding VALID/READY handshakes (AXI/AMBA)
Hi everyone! I’ve been diving into the AXI4 protocol for a small design exercise, and while I’m making progress, I’m still trying to build a solid intuition for the VALID/READY handshake, especially on the less 'visible' channels like the Write Respo...
STUSB4500 IC failure in the field
Hi all, my team is experiencing some boards have failure of their STUSB4500 sink PD controller. We have not 100% determined the cause yet, but I found that our implementation is only using 0.1uF caps for the VREG 1V2 and VREG 2V7 decoupling. This is ...
