Target Connector Type

  • This is a standard 20 pin double row (two rows of 10 pins) connector (pin to pin spacing: 2.54mm/0.100").
  • If terminal strip without shroud is used, the spacing marked with "A" must be a minimum of 30.6mm/1.2".
  • Examples with housing: Samtec HTST-110-01-L-D (through-hole); Samtec HTST-110-01-L-DV (surface mount).
  • Examples without housing: Samtec TSW-110-23-L-D; Berg 67996-120H.

Interface Standard

The Debug Cable supports different interface standards:

1JTAGIEEE 1149.1alternate pin function: TMS, TCK
3Compact JTAGIEEE 1149.7alternate pin function: TMSC, TCKC
2Serial Wire DebugCoreSight ARMalternate pin function: SWDIO, SWCLK

The interface type and corresponding pin function can be selected in the debuggers GUI.

Smaller Footprint

For board designs requiring a smaller debug connector footprint we recommend to use the 20-pin or 10-pin MIPI connector
and to additionally use the converter
