The Tag-Connect TC2050-IDC-050-ALL is a 10-pin “legged” Plug-of-Nails™ programming/debug cable that mates directly to a tiny TC2050 PCB footprint—no header required—and terminates in a 0.05″ (1.27 mm) 2×5 IDC plug. It connects 1:1 with all ten conductors present (including grounds and detect), making it suitable for ULINK2 and other tools using a Samtec FTSH-105-01 style micro-header.
For space-constrained boards, eliminating a fitted header saves BOM cost and height while retaining a secure, repeatable connection for SWD/JTAG during bring-up, test and production. The legged form factor self-retains for hands-free use.
Also available in a No-Legs variant as TC2050-IDC-NL-050-ALL (use with a clip) and in a 20-pin micro-header version as TC2050-IDC-050-ALL-20. For ARM 20-pin (0.1″) pods, pair a TC2050 cable with the TC2050-ARM2010 adapter.
ARM Cortex-M SWD/JTAG, FPGA/CPLD bring-up, in-line production programming, and boundary-scan on compact or sealed designs where a permanent connector is undesirable.

No-legs versions need a retainer such as the TC2050-CLIP for hands-free operation. - 1568523: Which debuggers does this cable suit?***SIMP***Any pod with a 0.05″ (MIPI-10) micro-header—e.g., ULINK2 and similar. For ARM 20-pin (0.1″) pods, use a TC2050 cable with the TC2050-ARM2010 adapter. - 1568524: What does “ALL” signify?***SIMP***All ten conductors are present; grounds and detect lines are carried through. This simplifies compatibility versus selective-pin versions. - 1568525: What is “LEMTA”?***SIMP***A variant with ribbon reversal for Atmel-ICE compatibility. If you need Atmel-ICE, choose the LEMTA option. - 1568527: How is this different from leaving a 10-pin header on the board?***SIMP***You save BOM cost and height; the TC2050 footprint has effectively zero height yet remains robust for repeated use during development and production. - 1568528: Can I use it for SWD and full JTAG?***SIMP***Yes. The 10-pin mapping supports common SWD and JTAG signals. Always verify your tool’s pinout. - 1568529: Is there a 20-pin micro-header version?***SIMP***Yes: the TC2050-IDC-050-ALL-20">TC2050-IDC-050-ALL-020 mates to 0.05″ 2×10 micro-headers while only wiring pins 1-10 in the ribbon. - 1568530: What footprint files are available?***SIMP***See Tag-Connect’s footprint download packs and the TC2050-IDC datasheet for keep-out and drilling guidance. - 1568531: How does this compare with costlier test connectors?***SIMP***Compared with fitted high-density board connectors and fixtures, Tag-Connect offers a compact, repeatable interface without permanent hardware on the PCB.
