QFP64/TQFP64 footprint discrepancy issues
Some of the emulated devices have a TQFP64 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 TQFP64 device adapter require QFP64 footprints that are not compatible with
TQFP64 copper traces.
For this reason, when designing your board, plan to have a double trace
compatible with both QFP64 Yamaichi sockets and TQFP64 copper traces. A
specification for a compatible footprint is 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 TQFP64 package.
Device mode for TQFP64 packages
Once your programmed has been debugged, you may want to program some
devices and test them directly in your application without using the DVP. This
mode is called ‘Device Mode’.
Because Yamaichi sockets are QFP64, you will not be able to insert a TQFP64
device and ensure a perfect contact.
