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.
The following chart shows the various socket and board part
numbers that make up these adapters.

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.

Which adapter is correct for your package
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.
Logical Systems maintains a device to adapter cross reference in
our office and on our web site. Contact us or visit our web site to
