2.6 Mictor 38 connector
The Mictor 38 connector is a 38-way 0.635mm pitch socket which supports JTAG debug, Serial Wire
Debug, SWO trace, and up to 16-bit wide continuous-mode TPIU trace.
Warning
• DSTREAM-ST captures up to 4-bit wide trace (TRACEDATA[0-3]).
• The center ground pins of the Mictor socket must be solder-pasted on the same side of the PCB as the
connector. If you do not solder-paste on the same side of the PCB as the connector, it might cause
mechanical or signal integrity issues.
Typically, the socket used is a 2-767004-2 from TE Connectivity.
To use this connector with DSTREAM-ST, the supplied Mictor adapter must be used in conjunction with
both the Arm JTAG 20 debug cable and the CoreSight 20 debug cable.
