Overview
The Tag Connect TC-LATTICE Adapter is designed for use with the Lattice HW-USBN-2B Programming Cable.
The TC-LATTICE Adapter allows Lattice's HW-USBN-2B Programming Cable users to use Tag-Connect TC2030-IDC or TC2030-IDC-NL cable instead of the supplied flying lead solution for programming various Lattice Semiconductor devices.
The adapter has a 12-pin (2x6) 0.1" female header that plugs into the Lattice HW-USBN-2B programmer and supplies a 6-pin (2x3) 0.1" male box header suitable for use with Tag-Connect TC2030-IDC Plug-of-NailsTM Cables, eliminating the need for a physical connector on each and every target PCB.
By default, the TC-LATTICE adapter comes fitted with a 500 Ω resistor connected between VCC and GND. This resolves the issue of the Lattice HW-USBN-2B unexpectedly raising VCC on low-power targets and eliminates the need for the resistor to be fitted to each of your target PCBs, see:
