PA17C42-QD(-03 or -16) Data Sheet
44 pin PQFP or TQFP socket/40 pin DIP 0.6" plug
Supported Device/Footprints
Using this adapter several Microchip devices in a 44 pin QFP
package can be programmed on 40 pin DIP programmers.
Adapter Construction
The adapter is made up of 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.

There are several 44QFP packages. Some devices are available
in more that one 44QFP package. Lookup the lead span for the
package you will be using. Find the matching socket in the table
above. Find the adapter that includes that socket in the Adapter
Construction section.
