PA40-44-P64-Dx-QF Data Sheet

40 pin DIP socket/44 pin QFP plug

Supported Device/Footprints

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.

10.0mm or less 12.0mm or more

The QFP Plug’s leads are dimensioned as follows.

Adapter Construction

The adapter is made up of 2 or 3 sub-assemblies. They

assemble via connectors making the adapter modular. This way

the sub-assemblies can be replaced easily.

When disassembling the adapter take care not to bend the pins.

When reassembling the adapter note the pin 1 indicators to align

Note: QFP Pin 1 is in the lower right corner. Microchip packaged

the QFP with a 180 degree rotation from the DIP & PLCC.

QFP Plug

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.
