CSP? I don’t think so.
Technically the term CSP is about size, not necessarily whether it’s flip-chip or not. Either way, I see bond wires on a die in a relatively large package…
You’re right. I found it while looking after CSP LEDs but that just don’t seem to be one. And the maker doesn’t even claim that it is, so it’s purely my error. Blink and it will be fixed.
