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.
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.
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.

Ideal for compact designs and cost-sensitive production where a permanent connector would add size, cost and assembly time."}]}]} - key_feature_3: 14-Pin 0.1″ IDC Termination - key_feature_3_tooltip: {"type":"root","children":[{"type":"paragraph","children":[{"type":"text","value":"resents a standard 2×7 IDC female for quick connection to JTAG tools, adapters and harnesses. Reduces setup friction in labs and production by remaining compatible with common 14-pin workflows and adapters used across vendors."}]}]} - key_feature_4: Legged, Hands-Free Retention - key_feature_4_tooltip: {"type":"root","children":[{"type":"paragraph","children":[{"type":"text","value":"Plastic alignment legs latch into PCB holes to hold contact pressure without a fixture. Speeds bring-up and flash steps at the bench; reduces operator effort and improves contact stability for repeated cycles during prototype and NPI stages."}]}]} - key_feature_5: Rugged Spring Pogo Pins - key_feature_5_tooltip: {"type":"root","children":[{"type":"paragraph","children":[{"type":"text","value":"Spring-loaded contacts tolerate slight misalignment and wear while maintaining low contact resistance. Designed for repeated insertions in development and light-to-medium production without degrading target pads or requiring connector cleaning."}]}]} - key_feature_6: Short, Low-Skew Ribbon - key_feature_6_tooltip: {"type":"root","children":[{"type":"paragraph","children":[{"type":"text","value":"Approximately 200 mm ribbon length minimises signal skew and maintains signal integrity for JTAG/SWD at typical lab lengths. Reduces risk of crosstalk versus improvised leads; consistent wiring supports repeatable programming across stations."}]}]} - key_feature_7: Series Options & Pinouts - key_feature_7_tooltip: {"type":"root","children":[{"type":"paragraph","children":[{"type":"text","value":"Companion variants cover no-legs (-NL) use, 0.05″ STDC14 (-050) and 2 mm IDC. Enables a single PCB footprint strategy across tools and programs, simplifying DFM and allowing drop-in swaps as debugger ecosystems or fixtures change."}]}]} - key_feature_8_tooltip: {"type":"root","children":[{"type":"paragraph","children":[{"type":"text","value":"Widely used for MSP430 JTAG/ST-14 and many MCU/DSP families via adapters.

It saves area and per-unit cost while remaining robust for repeated use. - 1569188: When should I choose the no-legs version?***SIMP***Use the TC2070-IDC-NL if you mount the cable in a fixture or prefer manual pressure without latching legs. - 1569190: I’m designing for ST’s ST-Link V3 (STDC14). Which cable?***SIMP***Use the 0.05″ option TC2070-IDC-050 or consider the compact SWD-only TC2030-CTX-NL-STDC14 to shrink your PCB footprint. - 1569191: Does the TC2070-IDC support full 14-pin JTAG?***SIMP***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. - 1569192: How big is the footprint and what about keep-outs?***SIMP***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. - 1569193: Will it damage my PCB pads?***SIMP***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. - 1569194: How is this better than fitting a 2×7 header?***SIMP***No connector on the target saves cost and board area, avoids tall components, and removes a placement step—useful in compact or sealed products. - 1569195: Can I program in production without holding the cable?***SIMP***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. - 1569196: Is there a 2 mm IDC option?***SIMP***Yes—the TC2070 series includes 2 mm IDC variants; contact Debug Store for availability or see other TC2070 listings in our catalogue. - 1569200: What if I only need SWD on a tiny footprint?***SIMP***Use a 6-pin Cortex solution such as TC2030-CTX-NL-STDC14 to shrink your pads while staying compatible with STDC14 tools.
