44 pin QFP socket/44 pin QFP plug  
Supported Device/Footprints  
These adapters accept 44 pin QFP devices and have a  
removable 44 pin QFP solder-down plug. This allows QFP device  
to be inserted into and removed from a prototype easily.  
The QFP socket accepts packages with the dimension sets listed  
below:

Adapter Construction  
The adapter is made up of 4 sub-assemblies. They assemble via  
connectors making the adapter modular. This way the sub-  
assemblies can be replaced easily.  
44QF-16 10.0 mm typ 11.6 mm typ 13.2 mm typ  
PQFP  
The QFP plug will fit most 44 pin. 0.8mm pitch, QFP land  
patterns. Usually the pads extend from the body past the tip of  
the device leads. This plug will fit on pads that have a minimum  
span of 10.0mm or less and a maximum span of 12.0mm or  
more.  
When disassembling the adapter take care not to bend the pins.  
When reassembling the adapter note the pin 1 indicators to align  
the parts correctly.  
Inner pad span  
10.0mm or less  
Outer pad span  
12.0mm or more

Adapter Dimensions  
Solders to the QFP land pattern on the prototype. Additional QFP  
Plugs can be purchased separately.  
Adapter Wiring  
The adapter is wired 1 to 1. QFP socket pin 1 connects to QFP  
plug pin 1. Pin 2 to pin 2 and so on around the package.
