PA40Dx-44QF-34 Data Sheet 40 pin DIP socket/44 pin QFP plug Supported Device/Footprints Adapter Construction These adapters accept 40 pin DIP devices and have a removable 44 pin QFP solder-down plug. They allow DIP devices, or emulators with DIP plugs, to be used during development of QFP based products. The adapter is made up of 3 or 4 sub-assemblies. They assemble via connectors making the adapter modular. This way the sub-assemblies can be replaced easily. The following DIP device footprints are converted to the indicated QFP footprint. 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. Zilog: Z86C34/ C35/ C36/ C44/ C45/ C46 Footprint: Same device 44QFP The following chart lists the adapters described by this datasheet and their subassemblies. Other devices that require the same wiring and footprint would also be supported. 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 Adapter PA40DZ-44QF-34 PA40DP-44QF-34 Test Socket 40-ADZ * none * Board QFP Plug PA51-DP-34Q PQF-44 PA51-DP-34Q PQF-44 * The top board always has a 40 pin DIP production socket.
