The TC2050-IDC-NL-050 programming cable has a 0.050″ pitch ribbon connector suitable for ULINK2 and similar debuggers that use the Samtec FTSH-105-01 style micro-header.
This cable is the equivalent to using our TC2050-ARM2010 adapter with a TC2050-IDC-NL cable connected to the ULINK2's 20-pin 0.1″ pitch traditional ARM JTAG header.
The pin connections are 1-1. Pins 5 and 9 of the TC2050 are not connected.
