Hmmm... when designing various printed circuit board. It
would be nice if I could at least search for parts, with
the
same pinouts.
As for why I thought about this? Well I noticed that quite
a
lot of LDO linear regulators ( SOT353 package) have
similar
pinout (so you could pretty much
swap em up, and be
good
as gold {after checking specs of course})
Still, most searches don't really tell you what parts have
same pinouts...
So what would be great, is if we can have a wiki where
you
can look up on common parts, and design your circuit
around pinouts that is easy to source. ( Again with the
addium, that you shouldn't limit yourself to easy to find
parts).

This would be useful for reverse engineering things where
they've ground off the part numbers. [+] |

[+] but you'd need to somehow agree on standardized names
for pinouts (eg "input"/ "in"/"signal"/"control" and "Vss"/"V+"
etc) |

Or use some kind of fuzzy or thesaurus-based matching… |

But sometimes you don't even know if a pin is an input or
an output, and all you've got is what components it's
connected to. For
certain chips, that's helpful, but the search engine would
need some way to understand that stuff. With
microcontrollers, it would be especially difficult, because
the GPIO pins can be inputs, outputs, or even both
depending on the application. I guess the search engine
would just have to ignore those if the chip is suspected to
be a microcontroller that has a GPIO pin in that location. |
