Debug Header Target Footprints
INTRODUCTION
To connect a debug header directly to a target board (without the use of a transition
socket) the following information will be helpful.
• DIP Device Footprints
• TQFP/PLCC Device Footprints
DIP DEVICE FOOTPRINTS
DIP device adapter footprints shown will accept adapter plugs like Samtec series APA
plugs. These plugs can be soldered in place during development/emulation and
eliminate the need for any other sockets.

TQFP/PLCC DEVICE FOOTPRINTS
TQFP/PLCC device adapter footprints shown will accept board stackers like Samtec
series DWM 0.050 Pitch Stackers. These stackers can be soldered in place during
development/emulation and eliminate the need for any other sockets.
