PA40-44-P64-Dx-QF Data Sheet
40 pin DIP socket/44 pin QFP plug
Supported Device/Footprints
Adapter Dimensions
The PA40-44-P64-Dx-QF adapter accepts 40 pin DIP devices
and has a removable 44 pin QFP solder-down plug. This allows
DIP devices, or emulators with DIP plugs, to be used during
development of QFP based products. Other devices that require
the same wiring and footprint would also be supported.
The following DIP device footprints are converted to the
indicated QFP footprint.
Microchip: PIC16C64,PIC16C64A, PIC16C65, PIC16C65A,
PIC16C74, PIC16C74A, PIC16C77
Footprint: Same device 44MQFP
This 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.

Adapter Construction
The adapter is made up of 2 or 3 sub-assemblies. They
Note: QFP Pin 1 is in the lower right corner. Microchip packaged
the QFP with a 180 degree rotation from the DIP & PLCC.
assemble via connectors making the adapter modular. This way
the sub-assemblies can be replaced easily.
Adapter Wiring
The following chart shows the connections from the DIP device
to the adapter’s QFP plug.
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.

QFP Plug
-
N/C
The QFP plug is removable. One is included with the adapter.
Additional QFP plugs may be ordered as PQF-44. This allows
the adapter to be used on several prototypes without de-
soldering.
