Key Features
Overview
The Tag-Connect TC2050-ARM2010 is an adapter that lets you use Tag-Connect TC2050 10-pin Plug-of-Nails™ cables with debuggers that present the standard 20-pin (0.1″) ARM JTAG header. It supports both JTAG and SWD workflows and maps the ARM20 signals to the TC2050 footprint, including SWDIO/TMS, SWCLK/TCK, SWO/TDO, nRESET and optional nTRST.
Two solder-bridge options provide flexibility: pin 5 of the TC2050 footprint can be configured as GND (for signal integrity) or as debugger power feed (some tools source 3.3 V or 5 V); and pin 9 can optionally carry nTRST when required. The board is intended for use with Tag-Connect TC2050-IDC and TC2050-IDC-NL cables to eliminate a mating connector on the target PCB.
If you prefer a smaller 6-pin SWD footprint, consider the related ARM20-CTX 20-pin to TC2030-IDC adapter with TC2030-IDC-NL cables. For ULINK-style 0.05″ headers, see TC2050-IDC-050 or, where all pins are needed, TC2050-IDC-050-ALL.
Engineers choose TC2050-ARM2010 to keep target boards compact while maintaining a standard connection back to popular tools such as J-Link, ST-LINK and PEmicro. The result is a familiar debugger interface on the tool side with a space-saving Tag-Connect footprint on the PCB.

Frequently Asked Questions
Have a Question?
-
Where can I find the signal map?
The adapter’s datasheet includes full pin tables for ARM20 ↔ TC2050 in both JTAG and SWD modes.
-
Can I use it with a 10-pin 0.05″ Cortex header on the tool?
If your debugger exposes a 10-pin 0.05″ header only, use an appropriate cable (e.g. TC2050-IDC-050 series) instead of ARM20, or employ the debugger vendor’s 20-to-10 adapter before TC2050-ARM2010.
-
How does this compare to more expensive needle/patch adapters?
Needle/patch boards (e.g. dedicated J-Link adapters) route ARM20 to Cortex-10 or needle pads. TC2050-ARM2010 uniquely maintains a Tag-Connect interface and adds selectable power/nTRST bridges—useful if you already design TC2050 footprints.
-
Do I need nTRST?
Many Cortex-M designs operate without nTRST. Some cores or older devices benefit from it; the bridge lets you enable it when required.
-
How much power can be fed via pin 5?
Use the power capability of your debugger as the limit. Some tools source 3.3 V rather than 5 V; check your probe’s manual before enabling power.
-
What is the purpose of the solder-bridges?
One bridge selects TC2050 pin 5 as GND or as debugger-supplied power. Another enables nTRST on pin 9 for targets that need TAP reset.
-
Does it work for SWD as well as JTAG?
Yes. The adapter routes the required SWDIO, SWCLK, SWO and nRESET lines for SWD, and the full TMS/TCK/TDI/TDO set for JTAG.
-
Is it compatible with J-Link, ST-LINK or PEmicro?
Yes. Any tool that exposes the standard 20-pin ARM JTAG header is supported.
-
What does the TC2050-ARM2010 do?
It adapts the standard 20-pin ARM JTAG header from a debugger to a Tag-Connect TC2050 10-pin footprint on the target, supporting both JTAG and SWD.
