The TC-LATTICE-10 Adapter allows users of Lattice's HW-USBN-2B Programming Cable to use Tag-Connect TC2050-IDC or TC2050-IDC-NL 10-pin cables instead of the supplied flying lead solution for programming various Lattice Semiconductor devices.
The adapter has a 12-pin (2×6) 0.1″ female header that plugs into the Lattice HW-USBN-2B programmer and supplies a 10-pin (2×5) 0.1″ male box header suitable for use with Tag-Connect TC2050-IDC Plug-of-Nails™ 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 Ohm 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 PCB's –
