Debug Connector Arrangements

A number of standard debug connector configurations are defined to allow in-circuit debuggers to connect to target boards easily. Most of the Cortex^®-M microcontroller development boards use these standard pinouts. If you are designing your own Cortex-M microcontroller board, you should use one of these connector arrangements to make connection to the in-circuit debugger easier.

F.1. The 10-Pin Cortex^® Debug Connector

For PCB design with small size, the 0.05″-pitch Cortex debug connector is ideal. The board space required is approximately 10 × 3 mm (the PCB header size is smaller, only 5 × 6 mm) and is based on the Samtec micro header (Figure F.1).

The 10-pin Cortex debug connector (Figure F.2) supports both ...
