The only way to get their footprint is to use Ultra Librarian, which is garbage software. - - - Updated - - - jimkess said: Lead Frame Chip Scale Package(LFCSP) is non-standard vendor used convention. it is same as QFN Click to expand... There are no standards, ever, period.

But either in the datasheet or on the web sites they refer to footprint drawings. Klaus
