10-Pin Cortex Debug Connector
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).
The 10-pin Cortex Debug Connector is supported by ULINK2 and ULINKPro.
20-Pin Cortex Debug + ETM Connector
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).
The Cortex Debug + ETM Connector is supported by ULINKPro.
20-Pin ARM Standard JTAG Connector
The ARM standard JTAG connector provides support for Serial Wire and JTAG interface modes in a 20-pin (0.1") connector. It has been used for many years in ARM processor-based systems and can be used to access all SWD, SWV, and JTAG signals available on a Cortex-Mx device.
Dimensions of the ARM JTAG connector are 1.29" x 0.722" (33 mm x 18.5 mm).
The ARM standard JTAG connector is supported by ULINK2, ULINK-ME, and ULINKPro.
38-Pin ARM ETM Mictor Connector
The Mictor (Matched Impedance ConnecTOR) has been the standard way to connect a trace probe to an ARM target. It supports up to 32-bit ETM trace and is really intended for use with very high-speed ARM processors such as Cortex-R4 and Cortex-A9. Cortex-M7 supports 16-bit data trace using the Mictor connector. This is only available with DS-5 using a DSTREAM debug and trace unit.
