Key Features
Overview
Streamline Your Lattice FPGA Programming Workflow
The Tag-Connect TC-LATTICE Adapter revolutionises FPGA programming by enabling seamless integration between Lattice's HW-USBN-2B Programming Cable and Tag-Connect's innovative TC2030 Plug-of-Nails™ cables. This compact adapter eliminates the need for traditional flying lead connections, delivering a more efficient and reliable programming solution for Lattice Semiconductor devices.
Enhanced Programming Efficiency
Featuring a 12-pin (2×6) 0.1″ female header input and 6-pin (2×3) 0.1″ male box header output, this adapter provides secure connectivity whilst maintaining signal integrity. The built-in 500 Ohm resistor between VCC and GND addresses the well-documented issue of the HW-USBN-2B unexpectedly raising VCC on low-power targets, eliminating the need for additional resistors on each target PCB.
Compatible with both TC2030-IDC and TC2030-IDC-NL cables, the TC-LATTICE adapter supports various programming requirements whilst significantly reducing PCB footprint requirements. For engineers working with 10-pin target board configurations, the complementary TC-LATTICE-10 adapter provides similar functionality with expanded connectivity.
Professional Engineering Solution
This adapter represents a compelling investment for electronic design engineers seeking to optimise their FPGA programming infrastructure. By eliminating physical connectors on target PCBs, engineers can reduce both board costs and space requirements whilst maintaining professional programming capabilities essential for development and production environments.

Questions and Answers
-
What Software Tools Are Compatible with This Programming Solution?
The adapter is passive, so it is transparent to whatever Lattice tool drives the HW-USBN-2B, for example Diamond Programmer or Radiant Programmer. It only provides the mechanical and electrical interface between the HW-USBN-2B and the Tag-Connect cables.
Side Connector To the HW-USBN-2B 12-pin (2x6) 0.1 in female header To the TC2030 cable 6-pin (2x3) 0.1 in male box header On board 500 ohm resistor between VCC and GND -
Can I Use This Adapter for Debugging as Well as Programming?
Yes for JTAG access. The HW-USBN-2B is a programming cable, and anything it does over JTAG goes through the adapter unchanged. Legged TC2030-IDC cables hold securely, which suits long sessions.
-
What Happens If I Need 10-pin Connectivity Instead of 6-pin?
Use Tag-Connect's TC-LATTICE-10 adapter. It does the same job for 10-pin target boards and connects to the TC2050-IDC and TC2050-IDC-NL cables.

Is Additional Power Supply Required for the Adapter?
No. The adapter is passive and needs no power of its own. The built-in 500 ohm resistor simply sits across VCC and GND.
-
What Lattice Devices Are Compatible with the TC-LATTICE Adapter?
Tag-Connect states it works with various Lattice Semiconductor devices programmed by the HW-USBN-2B over JTAG. For SPI programming use the 10-pin TC-LATTICE-10, which adds the SN/PROG and DONE signals. I2C is not covered by either, as Tag-Connect's cables cover JTAG and SPI programming only.

-
What Is the Purpose of the Built-in 500 Ohm Resistor?
It fixes a known issue where the Lattice HW-USBN-2B programmer can unexpectedly raise VCC on low-power target devices. The 500 Ohm resistor sits between VCC and GND, so you don't need to fit a resistor on each target PCB. Lattice's official support documentation refers to this issue.
-
Can I Use Both Legged and No-legs Tag-Connect Cables with This Adapter?
Yes. The TC-LATTICE adapter works with both TC2030-IDC (legged) and TC2030-IDC-NL (no-legs) cables. Legged cables hold securely for debugging sessions, while no-legs cables need the smallest PCB footprint and suit production programming.
-
How Does the PCB Footprint Compare to Traditional Programming Headers?
A TC2030 no-legs footprint needs only 0.02 sq in, about the size of an 0805 resistor. The legged TC2030 footprint is 0.09 sq in. Either is much smaller than a traditional 10-pin or 20-pin JTAG header, which helps in space-constrained designs.
Footprint Board area TC2030 no legs 0.02 sq in (about an 0805 resistor) TC2030 legged 0.09 sq in -
Is the TC-LATTICE Adapter Suitable for Production Programming Environments?
Yes. The spring pins are rated for over 100,000 operations, which suits high-volume production programming. Because no physical connector is needed on the target board, per-board cost is also lower.
