Info on 1212 needed

by robert_flex on Tue Aug 02, 2016 9:42 am

Concerning the 1212 adapter board: What is the pin spacing of the MSOP/TSSOP side of the adaptor? Is there a datasheet for this adapter showing the overall dimensions?

Thanks,

Robert

The pin spacing for all TSSOP/MSOP packages is 0.025" (40 pins per inch), or 0.635mm.

There's no single datasheet that lists all chip footprints (at least not one that doesn't cost a few hundred dollars from the standards organizations), but any chip in a TSSOP/MSOP package should have a measured drawing toward the end.

In a pinch, ON Semiconductor and NXP have good dimensional information in their datasheets. TI provides good drawings, but they make up their own package names, and it takes about fifteen minutes of reading cross-references to find out if you have the right one.

I think the library used to make the breakouts is part of the Adafruit Eagle library, but here's a copy in case it isn't:
