Tag-Connect TC2030-CTX 6-Pin Cable for Arm Cortex SWD (Legged or No Legs)
Tag-Connect TC2030-CTX 6-Pin Cable for Arm Cortex SWD (Legged or No Legs)
SKU: TC2030-CTX
From £46.75 exc VAT
Four legs clip into latch holes on the board, so the cable stays in place hands-free. Best for development and debugging, where the cable stays connected for long periods.
Fits a smaller footprint (0.02 sq in) with no leg latch holes. For production programming, and for debugging when held in place with a TC2030-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 become 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.
10-pin 0.05 in connector wired to the standard Cortex Debug pinout, for the Keil ULINK2, Cypress MiniProg3 and MiniProg4 and other probes with the standard 10-pin Cortex header.
The 10-pin connector is fitted reversed to suit the Microchip Atmel-ICE, whose header numbering is reversed relative to the standard Cortex Debug header. 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 TC2030-CTX links an Arm Cortex debugger with the 10-pin 0.05 in Cortex Debug header to six pads on your PCB. Spring-loaded pins contact the pads, so the board carries no debug header. It carries SWD with SWO and nRESET.
Choose Legged or No Legs, standard or Soft Squeeze tabs, and the standard or Atmel-ICE (LEMTA) ribbon in the options above.
The Legged version clips into a 0.09 sq in footprint and stays in place without a fixture. The No Legs version needs only 0.02 sq in and is held by hand, with a TC2030-CLIP or in a fixture. For an ST-LINK/V3 use the TC2030-CTX-STDC14; for a 20-pin 0.05 in Cortex probe, the TC2030-CTX-20.
SWD From a 10-Pin Cortex Debug Probe to Six Pads on Your PCB
The Tag-Connect TC2030-CTX connects an Arm Cortex debugger with the 10-pin 0.05 in Cortex Debug header to a 6-pad TC2030 footprint on your PCB, with no connector fitted to the board. The ribbon connector at the tool end mates with the FTSH-105 style micro-header used on the Keil ULINK2 and other Cortex debug probes. The cable carries SWD with SWO and nRESET.
Options
| Option | Choice | Detail |
|---|---|---|
| Head | Legged | Four legs latch into holes in the PCB; footprint 0.09 sq in |
| Head | No Legs | No latch holes; footprint 0.02 sq in; hold by hand, with a TC2030-CLIP or in a fixture |
| Squeeze | Standard tabs | Regular-tension squeeze tabs on the Legged head; holds through long debug sessions |
| Squeeze | Soft Squeeze | Softer tabs for frequent production programming; Legged only, not suited to debugging |
| Ribbon | Standard | 10-pin connector wired to the standard Cortex Debug pinout |
| Ribbon | LEMTA (for Atmel-ICE) | 10-pin connector fitted reversed to suit the Microchip Atmel-ICE, whose header numbering is reversed |
Pin Assignment
| TC2030 Pad | Signal | 10-Pin Cortex Debug Connector Pin |
|---|---|---|
| 1 | VCC | 1 |
| 2 | SWDIO / TMS | 2 |
| 3 | nRESET | 10 |
| 4 | SWCLK / TCK | 4 |
| 5 | GND | 3, 5 and 9 (GNDDetect) |
| 6 | SWO / TDO | 6 |
Connector pins 7 (RTCK) and 8 (TDI) are not connected, so the cable carries SWD, not full 4-wire JTAG.
Pinout, footprint and wiring diagram: TC2030-CTX pinout.
PCB footprint: the TC2030-CTX uses the same footprints as the TC2030-IDC (Legged) and TC2030-IDC-NL (No Legs). No solder paste on the contact pads. Tag-Connect says the No Legs footprint saves over 66% of the board space of a typical FTSH-105 10-pin micro-header. The footprint drawings are in the TC2030-IDC and TC2030-IDC-NL datasheets under Downloads. See also our Tag-Connect cable guide.
Spring-Pin Contacts
Each cable has six spring pins. Tag-Connect's cycle testing shows them lasting well over 100,000 connections. On the Legged version the legs hold the plug on the board during programming or debugging, so no fixture or hand pressure is needed.
Atmel-ICE users: the Atmel-ICE's 10-pin header numbering is reversed relative to the standard Cortex Debug header. Order the LEMTA ribbon, which has the connector fitted reversed. Tag-Connect warns that a standard Cortex cable plugged into an Atmel-ICE will short out power and other signals.
Who It's For
Engineers who program or debug Arm Cortex-M boards over SWD through a 6-pad TC2030 footprint, from a probe with the 10-pin 0.05 in Cortex Debug connector.
| Device Family | Debugger or Programmer | Ribbon |
|---|---|---|
| Arm Cortex devices with SWD | Keil ULINK2, and other probes with the 10-pin Cortex Debug (MIPI-10) connector | Standard |
| Infineon (Cypress) PSoC 4, PSoC 5LP and PSoC 6, and Cypress Arm MCUs, SWD | Cypress MiniProg3, MiniProg4 | Standard |
| Microchip SAM (Arm Cortex), SWD | Microchip Atmel-ICE, SAM port | LEMTA |
Limitations
Not the right cable for an ST-LINK/V3 (use the TC2030-CTX-STDC14 or TC2030-CTX-NL-STDC14), a probe with the 20-pin 0.05 in Cortex header such as the IAR I-jet or Keil ULINKpro (use the TC2030-CTX-20), a SEGGER J-Link with the 20-pin 0.1 in ARM header (use the TC2030-IDC with the ARM20-CTX adapter), 4-wire JTAG (use the 10-pin TC2050-IDC-050-ALL), or ETM trace (use the TC2030-CTX-ETM).

Questions and Answers
-
Which Version Do I Need for the Atmel-ICE?
Choose the LEMTA ribbon and use the Atmel-ICE's SAM port. The Atmel-ICE numbers its 10-pin header in reverse, and the LEMTA cable has its ribbon connector fitted reversed to correct for that. Tag-Connect warns that a standard cable plugged into an Atmel-ICE will short out power.
-
When Should I Choose Soft Squeeze?
For frequent production programming on a legged footprint. Tag-Connect designed the softer tabs to be easy on operators' fingers and says they can also suit very dry or cold conditions, where standard tabs become stiffer. It does not recommend them for debugging, because an accidental tug can disconnect the cable, or for humid environments.
-
What PCB Features Do I Need on the Target?
Provide the six contact pads and the three alignment pin holes; the Legged version also needs four leg latch holes. Follow Tag-Connect's TC2030-IDC (Legged) or TC2030-IDC-NL (No Legs) footprint drawing.
Footprint Contact pads Alignment pin holes Leg latch holes Legged (TC2030-IDC) 6 3 4 No Legs (TC2030-IDC-NL) 6 3 None -
Is There a Recommended Method to Hold No Legs Versions?
Yes. The TC2030-CLIP board fits onto the three alignment pins from underneath the PCB and holds a No Legs cable in place for hands-free debugging. It is offered as an add-on when you choose No Legs.
-
Is Polarity Fool-Proof on the Target?
Yes. Tag-Connect says the connector is designed so it can only be inserted the correct way round. The three alignment pins sit in an asymmetric pattern, so the plug will not seat if it is turned round.
-
Does the TC2030-CTX Carry Full JTAG?
No. Connector pins 7 (RTCK) and 8 (TDI) are not connected, so the cable carries SWD with SWO and nRESET, not 4-wire JTAG. For JTAG from a 10-pin Cortex Debug probe use the 10-pin TC2050-IDC-050-ALL, which connects all ten pins.
-
Which Debuggers Does the 10-Pin End Suit?
Probes with the standard 10-pin 0.05 in Cortex Debug (MIPI-10) header: the Keil ULINK2, the Cypress MiniProg3 and MiniProg4, and similar probes. For the Microchip Atmel-ICE choose the LEMTA ribbon. Check your probe's connector before ordering.
-
How Do I Use It with ST-LINK/V3 (STDC14)?
Not with this cable. The ST-LINK/V3 has a 14-pin STDC14 connector, so order the TC2030-CTX-STDC14 (Legged) or TC2030-CTX-NL-STDC14 (No Legs). Both use the same 6-pad TC2030 footprint on your board.
-
Can I Access Trace (ETM)?
Not with this cable. The TC2030-CTX-ETM has a 20-pin 0.05 in Cortex connector, a 6-pin TC2030 plug for SWD and a second 10-pin TC2050 plug that carries the ETM trace signals from pins 11 to 20. It suits probes such as the IAR I-jet and Keil ULINKpro.
