Target Connector Type
- This is a standard 20 pin double row (two rows of 10 pins) connector (pin to pin spacing: 2.54mm/0.100").
- If terminal strip without shroud is used, the spacing marked with "A" must be a minimum of 30.6mm/1.2".
- Examples with housing: Samtec HTST-110-01-L-D (through-hole); Samtec HTST-110-01-L-DV (surface mount).
- Examples without housing: Samtec TSW-110-23-L-D; Berg 67996-120H.
Interface Standard
The Debug Cable supports different interface standards:
The interface type and corresponding pin function can be selected in the debuggers GUI.
| 1 | JTAG | IEEE 1149.1 | alternate pin function: TMS, TCK |
| 3 | Compact JTAG | IEEE 1149.7 | alternate pin function: TMSC, TCKC |
| 2 | Serial Wire Debug | CoreSight Arm® | alternate pin function: SWDIO, SWCLK |
The interface type and corresponding pin function can be selected in the debuggers GUI.

Smaller Footprint
For board designs requiring a smaller debug connector footprint we recommend to use a 20-pin or 10-pin MIPI connector via one of the following converters:
LA-2729 Converter IDC20A to MIPI-10/20T (Recommended, since easy and robust)
LA-3770 Converter IDC20A to MIPI-10/20D/34 (Use only if you need legacy debug signals RTCK, DBGRQ, DBGACK, TRST)
Learn more about the differences between the two converters in the Lauterbach knowledge base.
