TQFP44 footprint issues
Some of the emulated devices have a TQFP footprint and require you to solder a
Yamaichi socket onto your application board. However, be aware that you may
encounter problems owing to the fact that the Yamaichi sockets used to connect
the TQFP44 device adapter require footprints that are not compatible with TQFP
copper traces.
For this reason, when designing your board, plan to have a double trace
compatible with both Yamaichi sockets and TQFP copper traces. Specifications for
compatible footprints are provided below. If you use compatible footprints, a single
printed circuit board design will serve for both the development stage and the final
product. When you are finished the development stage, you can simply replace the
development Yamaichi socket by the programmable target device in an actual
TQFP44 package.
