The TC2050-2x10 adapter bridges the gap between traditional 20-pin JTAG/SWD debuggers and Tag Connect's space-saving 10-pin footprint technology. This professional-grade adapter board allows engineers to utilise two TC2050-IDC cables simultaneously, providing dual programming and debugging capabilities through a single 20-pin ribbon interface.
The adapter maintains full signal integrity across all JTAG and SWD protocols, supporting both traditional JTAG debugging and ARM's Serial Wire Debug interface.
Designed for production environments and development labs, the TC2050-2x10 eliminates PCB real estate waste whilst preserving debugging functionality. The adapter works seamlessly with legged or no-legs TC2050-IDC variants, offering flexibility for different production requirements. For complete debugging solutions, pair with TC2050-IDC cables and explore our comprehensive range of Tag Connect adapters for various microcontroller families.

For no-legs variants, you may need TC2050-CLIP retaining clips for hands-free debugging. - 1572646: Does the adapter support both JTAG and SWD protocols?***SIMP***The TC2050-2x10 maintains full compatibility with both JTAG (4-wire) and SWD (2-wire) debugging protocols, automatically adapting based on your debugger and target configuration. - 1572647: What is the pin mapping between the 20-pin input and dual 10-pin outputs?***SIMP***The 20-pin connector maps pins 1-10 to header J1 (rightmost) and pins 11-20 to header J2 (leftmost), maintaining standard ARM JTAG pinout assignments. - 1572648: Can I debug two different microcontroller families simultaneously?***SIMP***Yes, each 10-pin output operates independently, allowing debugging of different ARM cores, microcontroller families, or even mixed ARM/non-ARM systems simultaneously. - 1572649: What cables do I need to purchase separately?***SIMP***The adapter requires two TC2050-IDC or TC2050-IDC-NL cables for complete operation. These connect between the adapter headers and your target PCBs' Tag Connect footprints. - 1572651: Is the adapter suitable for production programming?***SIMP***Absolutely. The robust PCB design and reliable connections make it ideal for production environments requiring dual target programming or testing workflows. - 1572652: How does this compare to using two separate single adapters?***SIMP***The TC2050-2x10 provides a more compact solution than dual adapters, reducing cable clutter and bench space whilst maintaining identical functionality and signal integrity. - 1572653: Does the adapter provide target power to connected devices?***SIMP***The adapter passes through the debugger's power pins (typically pin 19 at +5V or +3.3V), but actual power delivery depends on your specific debugger's capabilities and configuration. - 1572654: What is the maximum cable length I can use with this adapter?***SIMP***Standard TC2050-IDC cables are 8 inches long. For longer distances, consider the signal integrity requirements of your specific debugging protocol and target clock frequencies.
