# Title: Tag-Connect TC2030-MCP-SWD Plug-of-Nails SWD Cable ## Description: What it is The Tag-Connect TC2030-MCP-SWD is a 6‑pin plug‑of‑nails cable with self‑retaining legs that mates to the tiny TC2030 footprint on the target PCB and routes Serial Wire Debug (SWD) signals to Microchip debuggers that use a modular jack, enabling fast, reliable ARM Cortex/Microchip SAM programming and debugging without any mated header on the board. Terminology: “Plug‑of‑nails” uses spring pogo pins pressed into a defined PCB footprint; the MCP suffix denotes the Microchip modular‑plug family; SWD denotes ARM’s 2‑wire debug interface (SWDIO/SWCLK plus nRESET, SWO, VTref, GND). Where it fits in the range Use this cable when a legged, self‑holding TC2030 is preferred for extended debug sessions and the host debugger expects a Microchip modular plug; for “no‑legs” production use, see the TC2030‑MCP‑SWD‑NL variant; for 10‑pin Cortex ribbon hosts, see the TC2030‑CTX family. Target‑side pinout (TC2030 footprint) TC2030 Pin Signal Description 1 VTref Target I/O reference (sense) 2 SWDIO Serial Wire Data I/O 3 nRESET System reset (active low) 4 SWCLK Serial Wire Clock 5 GND Ground (also GNDDetect) 6 SWO Serial Wire Output (trace) This TC2030 SWD pin map matches the TC2030‑CTX ARM Cortex scheme, allowing a single tiny 6‑pad footprint to support multiple host adapters. Wiring quick‑start Place the TC2030‑MCP‑SWD on the target footprint aligning the three steel guides; press until the four legs snap into their holes and the pogo pins seat. Connect the modular plug end to the supported Microchip debugger interface or adapter designed for SWD use. Power the target or enable power‑through if supported; the host will sense VTref on pin 1. Start a debug session using SWD mode in MPLAB X (for SAM/ARM targets) or the appropriate toolchain. Tip: For rapid production flashing with minimal operator fatigue, consider the no‑legs variant plus a retention clip; for long debugging sessions, the legged cable is self‑retaining.

If the host expects a 10‑pin Cortex ribbon, use TC2030‑CTX (same target pinout).

The Tag-Connect TC2030-MCP cable is primarily intended for use in development environments and is also ideal for production programming. The spring-loaded contact pins are held firmly in place by four plastic legs each of which clips securely into its own locating hole.

legged-footprint-copy.jpg

Tag-Connect TC2030-MCP is ideal where you need to maintain a connection to the PCB for an extended period such as when performing testing or development work.

See also TC2030-MCP-NL for applications where an even smaller footprint is required.

Ideal for both debugging and production programming.

The Tag‑Connect TC2030‑MCP‑SWD brings ARM Cortex/SAM SWD signals to the tiny TC2030 footprint, combining a legged, self‑retained plug‑of‑nails on the target with a Microchip‑style modular plug on the host side for debuggers that support SWD, streamlining bring‑up and production without any PCB header.

Engineers standardise on the TC2030 SWD pin map (VTref, SWDIO, nRESET, SWCLK, GND, SWO) so the same footprint works with alternative host adapters like the TC2030‑CTX family when a 10‑pin Cortex ribbon is required, reducing variants and documentation overhead.

TC2030-MCP-SWD is wired for ARM/SAM SWD signals on the TC2030 footprint, whereas TC2030-MCP is for Microchip PIC ICSP; the target footprints can be identical, but the host/usage differs.

- 1570525: Do I need SWO connected?***SIMP***

No; SWO is optional for trace/ITM; basic SWD debug/program works with VTref, SWDIO, SWCLK, GND, and nRESET.

- 1570526: What’s the target-side pinout?***SIMP***Pin 1 VTref, 2 SWDIO, 3 nRESET, 4 SWCLK, 5 GND, 6 SWO; this matches the TC2030‑CTX SWD convention.
