Description
20-Pin Cortex
Debug + ETM
Connector
J50
This small 20-pin (0.05") connector provides access to
SWD, SWV, JTAG, and ETM (4-bit) signals available on a
Cortex-M3/M4/M7 device.
A 20-pin header (Samtec FTSH-110-01) is specified with
dimensions:
0.50" x 0.188" (12.70 mm x 4.78 mm).
NOTE - JTAG
– TRACE Signals
Due that the MCU ports used for the trace signals also are
shared with other interfaces. It is important to isolate these
signals/interfaces for the
J4-Cortex Debug D ETM
connector
.

10-Pin Cortex
Debug
Connector
J52
The Cortex Debug Connector provides support for Serial
Wire and JTAG interface modes in a very small, low cost
10-pin (0.05") connector. This new style connector provides
access to all SWD, SWV, and JTAG signals available on a
Cortex-Mx device.
A 10-pin header (Samtec FTSH-105-01) is specified with
these dimensions:
0.25" x 0.188" (6.35 mm x 4.78 mm).
