PnP QFN-32 4×4 0.4
QFN / DFN / LGA · 4.00 × 4.00 · 0.4 pitch · 32 pins
Package drawing
Top view, to scale, drawn by the same engine the app uses. Letters match the datasheet. In the app you can flip to the bottom view, which is how most datasheets draw it.

Center pad (EP) size is typical only; it varies most between makers.
Typical industry values for this package. Always confirm against the datasheet for the exact part number and suffix you are placing, and check the first board.
What to watch on QFN / DFN / LGA
- Reading a bottom-view drawing as if it were the top view, so pin 1 ends up mirrored
- Typing mils into a millimeter field
- Building a HotRod or flip-chip part as a normal QFN
- Leads so wide for the pitch that they bridge
