Tag-Connect TC2050-IDC-050-ALL 10-Pin Cable for 0.05 in Cortex Debug, All Pins (Legged or No Legs)
SKU: TC2050-IDC-050-ALL
From £70.00 exc VAT
Four legs clip into latch holes on the board, so the cable stays in place hands-free. Best for development and debugging.
Fits a smaller footprint (about 0.03 sq in) with no leg latch holes. For production programming, and for debugging when held in place with a TC2050-CLIP or in a fixture.
Regular-tension squeeze tabs on the Legged head. The legs stay latched until you squeeze the tabs, so the cable holds through long debug sessions as well as production programming. No Legs cables have no tabs, so this choice makes no difference to them.
Softer squeeze tabs, easier on operators' fingers in frequent production programming. Tag-Connect says they can also suit very dry or cold conditions, where standard tabs may be stiffer. The legs release more easily, so an accidental tug can disconnect the cable: not suited to debugging, and not recommended in humid environments. Legged cables only.
Ribbon connector in the standard orientation for the 10-pin 0.05 in Cortex Debug header: Keil ULINK2, Cypress MiniProg3 and MiniProg4 and similar probes.
The ribbon connector is fitted reversed to suit the Microchip Atmel-ICE, whose header numbering is reversed. Tag-Connect warns that a standard cable plugged into an Atmel-ICE will short out power and other signals.

Key Features
Overview
The Tag-Connect TC2050-IDC-050-ALL links a probe with the 10-pin 0.05 in Cortex Debug header to ten pads on your PCB, with all ten pins wired 1-to-1. Spring pins contact the pads, so the board carries no debug header. It carries SWD and JTAG.
Choose the head, squeeze tabs and ribbon in the options above.
The Legged version clips into the footprint and stays in place without a fixture. The No Legs version needs about 0.03 sq in and is held by hand, with a TC2050-CLIP or in a fixture. For a 20-pin 0.05 in probe use the TC2050-IDC-050-ALL-20.

All Ten Cortex Debug Pins From a 0.05 in Probe to Ten Pads on Your PCB
The Tag-Connect TC2050-IDC-050-ALL connects a debugger with the 10-pin 0.05 in (1.27 mm) Cortex Debug header, the Samtec FTSH-105 style micro-header, to a 10-pad TC2050 footprint on your PCB, with no connector fitted to the board. All ten conductors are wired 1-to-1, including pins 5 and 9, so it carries SWD and JTAG.

TC2050-IDC-050-ALL Pinout
TC2050 pad n goes to connector pin n. The table shows the signals when the cable is plugged into an Arm 10-pin Cortex Debug port, including the Atmel-ICE SAM port. On the LEMTA version the connector is fitted reversed to correct the Atmel-ICE's reversed numbering, so the pads carry the same signals. On the Atmel-ICE AVR port the pads carry that port's AVR signals instead, so check the Atmel-ICE user guide before laying out an AVR board.
| Pad and Pin | Signal | Pad and Pin | Signal |
|---|---|---|---|
| 1 | VTref | 2 | SWDIO / TMS |
| 3 | GND | 4 | SWCLK / TCK |
| 5 | GND | 6 | SWO / TDO |
| 7 | Key (no signal) | 8 | TDI |
| 9 | GNDDetect | 10 | nRESET |
On the footprint the pads are numbered 1 to 5 along one row and 6 to 10 back along the other, so pad 10 sits opposite pad 1. They are not arranged odd and even like the header: follow the footprint drawing.
PCB footprint: ten contact pads at 0.05 in pitch and three alignment holes; the Legged footprint adds four leg latch holes. Keep solder paste off the contact pads. The drawings are in the TC2050-IDC (Legged) and TC2050-IDC-NL (No Legs) datasheets under Downloads.
Spring-Pin Contacts
Tag-Connect quotes over 100,000 operations for the TC2050 spring pins. The 0.05 in connector uses fine-pitch ribbon with thin conductors, which Tag-Connect says can break over time with repeated flexing. If your debugger also has the 20-pin 0.1 in Arm JTAG header, the TC2050-IDC with the TC2050-ARM2010 adapter uses heavier ribbon and is the more durable choice, though that route leaves pins 5 and 9 unconnected.
Atmel-ICE users: the Atmel-ICE numbers its 10-pin header in reverse. Order the LEMTA ribbon, which has the connector fitted reversed. Tag-Connect warns that a standard cable plugged into an Atmel-ICE will short out power and other signals.
Who It's For
Engineers who program or debug boards over SWD or JTAG from a probe with the 10-pin 0.05 in Cortex Debug header, and want no debug header on the PCB.
| Device Family | Debugger or Programmer | Ribbon |
|---|---|---|
| Arm Cortex-M devices, SWD or JTAG | Keil ULINK2 and other probes with the 10-pin 0.05 in Cortex Debug (FTSH-105) header | Standard |
| Cypress (now Infineon) PSoC and other Cypress MCUs, JTAG. The SWD signals also pass through; for an SWD-only board Tag-Connect recommends the 6-pin TC2030-CTX | Cypress MiniProg3, MiniProg4 | Standard |
| Microchip SAM (Arm) devices from the Atmel-ICE SAM port, JTAG or SWD; AVR devices from the AVR port, JTAG, PDI, aWire, SPI or debugWIRE | Microchip Atmel-ICE | LEMTA |
Limitations
Not the right cable for a 20-pin 0.05 in Cortex probe (use the TC2050-IDC-050-ALL-20) or a debugger with only the 20-pin 0.1 in Arm JTAG header (use the TC2050-IDC with the TC2050-ARM2010 adapter). If your target must not see pins 5 and 9, use the TC2050-IDC-050, which leaves them unconnected.

| TC2050-IDC-NL-050-ALL | No Legs | None (no tabs) | Standard | Production programming, or debugging with a TC2050-CLIP; smallest footprint |
| TC2050-IDC-050-ALL-SOFT | Legged | Soft Squeeze | Standard | Frequent production programming on a legged footprint |
| TC2050-IDC-050-ALL-LEMTA | Legged | Standard tabs | LEMTA | Atmel-ICE: development and debugging |
| TC2050-IDC-NL-050-ALL-LEMTA | No Legs | None (no tabs) | LEMTA | Atmel-ICE: production programming, or debugging with a TC2050-CLIP |
| TC2050-IDC-050-ALL-LEMTA-SOFT | Legged | Soft Squeeze | LEMTA | Atmel-ICE: frequent production programming on a legged footprint |
All six versions use the same ten-pad contact pattern and connect all ten pins; only the head, the squeeze tabs and the ribbon orientation differ.

Questions and Answers
-
How Is This Different From Leaving a 10-Pin Header on the Board?
You save BOM cost and height. The TC2050 footprint has effectively zero height yet stands up to repeated use in development and production.
-
Can I Use It for SWD and Full JTAG?
Yes. All ten pins are wired 1-to-1, so the SWD signals (SWDIO, SWCLK, SWO) and the JTAG signals (TMS, TCK, TDO, TDI) all pass through. Check that your probe uses the Arm 10-pin Cortex Debug pinout shown in the description.
-
Is There a 20-Pin Micro-Header Version?
Yes, the TC2050-IDC-050-ALL-20 mates with the 20-pin 0.05 in micro-header (Samtec FTSH-110-01 style), but only pins 1 to 10 are wired.
TC2050-IDC-050-ALL (this cable) TC2050-IDC-050-ALL-20 Debugger connector 10-pin 0.05 in, Samtec FTSH-105-01 style 20-pin 0.05 in, Samtec FTSH-110-01 style Pins connected All 10, 1-1 Pins 1-10 connected 1-1; pins 11-20 not connected -
What Footprint Files Are Available?
The footprint drawings, with keep-out and drilling guidance, are in the TC2050-IDC (Legged) and TC2050-IDC-NL (No Legs) datasheets under Downloads on this page.
-
How Does This Compare with Costlier Test Connectors?
Compared with fitted high-density board connectors and fixtures, Tag-Connect offers a compact, repeatable interface without permanent hardware on the PCB.
-
What Does “Plug-of-Nails™” Mean?
It is Tag-Connect's name for its spring-pin (pogo-pin) plug, which presses onto a footprint of pads and alignment holes in the PCB, so no header is soldered to the board.
-
What Is the Difference Between the Legged and the No Legs Versions?
Legged versions latch into four holes in the PCB and hold themselves in place. No Legs versions need no latch holes and a smaller footprint, and are held by hand, with a TC2050-CLIP or in a fixture.
-
Which Debuggers Does This Cable Suit?
Probes with the 10-pin 0.05 in Cortex Debug (FTSH-105) header, for example the Keil ULINK2, Cypress MiniProg3 and MiniProg4, and the Microchip Atmel-ICE (order the LEMTA ribbon). For Arm 20-pin 0.1 in pods, use the TC2050-ARM2010 adapter with a TC2050-IDC cable (Legged or No Legs) rather than this 0.05 in cable.
-
What Does “ALL” Signify?
All ten conductors are connected, so pin 5 (GND) and pin 9 (GNDDetect) are carried through as well. The TC2050-IDC-050 leaves those two pins unconnected.
-
What Is “LEMTA”?
The LEMTA version has the ribbon connector fitted reversed to suit the Microchip Atmel-ICE, whose 10-pin header numbering is reversed. Choose it for an Atmel-ICE: Tag-Connect warns that a standard cable plugged into an Atmel-ICE will short out power and other signals.
