ST-LINK/V2 Cable Selection & Installation

The ST-LINK/V2 is an in-circuit debugger and programmer for the STM8 and STM32 microcontroller families.

We have a couple of simple, space-saving solutions to the ST-LINK/V2 for you.

1. Full traditional JTAG using our TC2050-ARM2010 adapter TC2050-IDC 10-pin Plug-of-Nails(tm) cables. Compatible with all ARM processors.
2. SWD (Serial Wire Debug) smaller footprint solution for Cortex processors. JTAG interface ARM20-CTX and the TC2030-IDC cable.
3. SWIM solution for STM8.

Both solutions are similar in that they use a 20-pin to Tag-Connect adapter. However, the Full Traditional JTAG also allows you to optionally power the target from the debugger and provides access to all of the signals provided by the traditional 20-pin ARM 0.1″ connection whereas the SWD (Serial Wire Debug)solution only supplies access to the signals used by the SWD protocol.

Full Traditional JTAG using TC2050 and TC2050-ARM2010 adapter

ST-LINK/V2 with TC2050-IDC 10 pin cable and TC2050-ARM2010 adapter

Both solutions for the ST-LINK/V2 are similar in that it requires an adapter and a cable, so it is up to you which one you will go for depending on your PCB needs. Here is the first solution:

ST-LINK/V2 with TC2050-ARM2010 adapter and TC2050-IDC 10 pin cable installed

Connect the TC2050-ARM2010 to the ST-LINK/V2 and connect the TC2050-IDC cable to the adapter.

Both “legged” and “no-leg” cables come in the standard 6″ length.
The TC2050-IDC-NL will require the TC2050-CLIP if you want a hands-free solution while debugging.

The TC2050-ARM2010 is a Tag-Connect adapter board allowing our TC2050-IDC cables to be used for ARM JTAG and ARM SWD (Serial Wire Debug) applications. Although intended for use with our patented TC2050-IDC Plug-of-Nails™ Cables, the adapter may be useful to people wishing to use 10-pin 0.1" ribbon headers on their PCB.

Tag-Connect's TC2050-IDC-NL "No Legs" Plug-of-Nails™ programming cable is a 10-conductor cable fitted with a spring-pin Tag-Connector that conveniently plugs directly into your PCB and terminates in a 0.1" ribbon connector.
  • Plugs straight to your PCB - No mating connector or header required!
  • Requires only a tiny 0.03" footprint of pads and locating holes in your PCB.
  • Zero Cost Per Board!
  • Tiny Footprint!
  • High-Reliability Spring-Pins make a Secure Connection and are rated for over 100,000 operations.
  • Footprint has no height and can reduce the size and space requirements of your PCB.
  • A great way to make test and debug signals available at no cost and with minimal board space.
  • Can be retained in place using a TC2050-CLIP board.
Tag-Connect cables provide a simple, reliable means of connecting Debuggers and Programmers or other test equipment to your PCB's while lowering board costs and facilitating efficient production programming. Tag-Connect uses a specially designed (Patent Pending) connector which eliminates the need for putting a programming header or other mating connector on every PCB. Instead, Tag-Connect uses tried and tested spring-pins rated for over 100,000 operations to make a secure connection to a special footprint pattern of pads and locating holes in your PCB. The tiny  "No Legs" footprint takes only 0.03 square inches (about the same board space as a couple of SMT resistors) which means you can locate the footprint right next to the MCU if desired. This 10-conductor cable has a TC2050-NL Tag-Connector on one end and a standard 0.1" ribbon connector on the other and is suitable for use with most many MCUs / FPGAs and JTAG programming and debug operations. A growing range of adaptors are available for specific and generic applications such as Xilinx SPARTAN and VERTEX FPGAs, TI MSP430 (TC2050-IDC-430), etc Also available in self-retaining "legged" version TC2050-IDC.

This product is intended to temporarily hold a TC2050-NL cable in place on a PCB. The solution will help when board space is premium and you need to perform a hands-free programming or debugging operation. For a more robust and convenient debugging connection consider using the TC2050 legged cable and footprint. We recommend keeping a few spare of these since they are easily misplaced when working on the desktop. Over time they may lose some grip.

ARM Cortex adapter to 6 pin plug-of-nails for ARM SWD1 x ARM20-CTX 20-Pin to TC2030-IDC Adapter for Cortex
The TC2030-IDC is our "Legged" 6-pin Plug-of-Nails™ programming cable fitted with a 6-pin 0.1" pitch ribbon connector. The "Legged" or "With Legs" versions of our cables snap directly into a tiny footprint of holes and pads in your PCB. By eliminating the need for a mating header component, you not only save PCB space but also cost on every board! See TC2030-IDC-NL for the "No Legs" version which has an even smaller footprint of about the size of an 0805 SMT resistor. Popular applications include programming Atmel AVR, many Renesas MCU's (when used with our TC-Renesas E1 / E8a adapter) and Zilog. Also great for bringing our SPI / IIC / RS232 and test signal access. Also available in 10" lengths (TC2030-IDC-10). Contact us for 36" length versions of these cables.

With its tiny 0.02 sq inch footprint the TC2030 Tag-Connector has a footprint using about the same PCB space as an 0805 resistor. The "No Legs" versions of our cables are designed to be held in place by hand for a fast programming operation or can be temporarily retained in place for debugging when used with our TC2030-CLIP boards. See TC2030-IDC for the "Legged" version which has four additional feet which hold it securely in place on the PCB for debugging or programming use. Popular applications include programming Atmel AVR, many Renesas MCU's (when used with our TC-Renesas E1 / E8a adapter) and Zilog.
