Key Features
Overview
The Tag-Connect TC2070-IDC is a 14-pin Plug-of-Nails™ programming/debug cable with integral alignment legs. It mates directly to a small PCB footprint—no mating header is required—then presents a 2×7 (0.1″) IDC female at the tool end for use with standard 14-pin JTAG connectors and adapters. A short ribbon section (≈200 mm) links the pogo-pin “plug” to the IDC.
Where It Fits
The TC2070 family is commonly used with MSP430, DSPs and other MCUs that expose a 14-pin JTAG/ST-14 interface. If you need the same footprint without the hands-free legs, choose the TC2070-IDC-NL. For ST’s 0.05″ STDC14 ecosystem, see the 0.05″ version TC2070-IDC-050. If you only require SWD on a tiny 6-pin footprint, consider the Cortex-specific TC2030-CTX-NL-STDC14.
Why Consider This Cable?
Compared with fitting a header on every PCB, Tag-Connect eliminates the target-side connector, saving board area and per-unit BOM cost while providing a robust spring-pin interface suitable for development and production. Engineers also value the keyed, repeatable connection and the availability of legged/no-legs variants and accessories for fixtures.

Questions and Answers
-
Will It Damage My PCB Pads?
No. The spring pins are designed for repeated cycles on ENIG/OSP pads. Use the legged version for stable pressure. For fixtures, the no-legs cable plus a retainer works well. -
How Is This Better Than Fitting a 2×7 Header?
There's no connector on the target, which saves cost and board area, avoids tall components and removes a placement step. This is useful in compact or sealed products. -
Can I Program in Production Without Holding the Cable?
Yes. Use the legged cable for bench work, or pair a no-legs cable with a retainer/mount in a fixture for hands-free production steps. -
Is There a 2 mm IDC Option?
Yes. The TC2070 series includes 2 mm IDC variants. Contact us for availability or see the other TC2070 listings in our catalogue. -
What If I Only Need SWD on a Tiny Footprint?
Use a 6-pin Cortex solution such as TC2030-CTX-NL-STDC14 to shrink your pads while staying compatible with STDC14 tools. -
What Is “Plug-of-Nails™” and Why Use It?
A spring-pin plug lands on a tiny PCB footprint, so you don't fit a header on each board. It saves board area and per-unit cost, and stands up to repeated use. -
When Should I Choose the No-legs Version?
Use the TC2070-IDC-NL if you mount the cable in a fixture or prefer manual pressure without latching legs. -
I’m Designing for ST’s ST-Link V3 (STDC14). Which Cable?
Use the 0.05″ option TC2070-IDC-050 or consider the compact SWD-only TC2030-CTX-NL-STDC14 to shrink your PCB footprint. -
Does the TC2070-IDC Support Full 14-pin JTAG?
Yes, its 14 pogo pins map to the 2×7 IDC end for legacy ARM-14/TI-14 style workflows. For UART alongside SWD, the 0.05″ STDC14 path can also expose TX/RX. -
How Big Is the Footprint and What About Keep-outs?
The TC2070 family uses a very small pad pattern with two or three tooling holes; follow the Tag-Connect footprint drawing for pad/NPTH sizing and keep-outs.
