Detail B
The EM260 package is a plastic 40-pin QFN that is 6mm x 6mm x 0.9mm. A large ground pad in the bottom
center of the package forms a 41
PCB ground plane. For more information, refer to the EM260 Reference Design.
Figure 13 illustrates the package drawing.

Notes
1. JEDEC ref MO-220
2. All dimensions are in millimeters
3. Pin 1 orientation identified by chamfer on corner of
exposed die pad.
4. Datum C and the seating plane are defined by the flat surface
of the metallised terminal
5. Dimension 'e' represents the terminal pitch
6. Dimension b applies to metallised terminal and is measured
1.25 to 1.30mm from terminal tip.
7. Dimension L1 represents terminal pull back from package
edge. Where terminal pull back exists, only upper half of lead is
visible on package edge due to half etching of leadframe.
8. Package surface shall be matte finish , Ra 1.6 - 2.2
9. Package warp shall be 1.150 maximum
10. Leadframe material is copper A194.
11. Coplanarity applies to the exposed pad as well as the
terminals.
