4. To be determined at seating place 'C'.
5. Dimension 'D1' and 'E1' do not include mold protrusions. Allowable protrusion is 0.25mm per side.
6. Detail of Pin 1 indicatifier are option all but must be located within the zone indicated.
7. Dimension 'b' does not include dambar protrusion. Allowable dambar protrusion shall not cause the
8. Exact shape of each corner is optional.
9. These dimension apply to the flat section of the lead between 0.10 mm and 0.25 mm from the lead tip.
10. A ll dimensions are in millimeters.
Table 4.4. QFP64 (Dimensions in mm)
The TQFP64 Package is 10 by 10 mm in size and has a 0.5 mm pin pitch.
The TQFP64 Package uses Nickel-Palladium-Gold preplated leadframe.
All EFM32 packages are RoHS compliant and free of Bromine (Br) and Antimony (Sb).
'D1' and 'E1' are maximum plastic body size dimension including mold mismatch. Dimension 'D1' and
'E1' shall be determined at datum plane 'H'.
lead width to exceed the maximum 'b' dimension by more than 0.08 mm. Dambar can not be located
on the lower radius or the foot. Minimum space between protrusion and an adjacent lead is 0.07 mm
