10-Pin 1.27Mm Coresight To 20-Pin 2.54Mm Arm Converter - TASKING iSYSTEM ARM HSSTP II User Manual

10-pin 1.27mm CoreSight to 20-pin 2.54mm ARM Converter

Related to the just described converter IASAM40HSSTP-JTAGSAM, the target development board
can also feature a 20-pin 2.54 mm ARM target debug connector instead of the 10-pin 1.27 mm
CoreSight. In order to connect the C part of the IASAM40HSSTP-JTAGSAM to this connector,
another converter IA10PINCS20PINARM-1 is required, converting from ARM 20-pin 2.54mm to 10-
pin 1.27 CoreSight. The IA10PINCS20PINARM-1 connects to the target and then the 'C' point of the
IASAM40HSSTP-JTAGSAM connects on top of it.
This converter is required only when the Active Probe is to be connected to the embedded target
providing the 20-pin 2.54 mm ARM target debug connector exposing only the debug interface
without the ARM HSSTP trace interface. No trace interface (e.g. SWO, parallel) is supported with this
converter. The converter is delivered along the Active Probe. Refer to
User Manual for more information.
