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. Inner pad span Outer pad span 10.0mm or less 12.0mm or more PA40-44-P64-DP-QF The QFP Plug’s leads are dimensioned as follows. Plug PQF-44 Body 10.0 mm typ Knee 9.6 mm typ Tip 12.0 mm typ Pitch 0.8 mm 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 the parts correctly. The following chart lists the adapters described by this datasheet and their subassemblies.

The optional test socket plugs into the production socket. Test Socket LSC # 40ADZ Style DIP ZIF Mfgr/Pn Aries 40-6554-11 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 desoldering.
