Overview
SEGGER has a wide variety of standard and proprietary connectors for its J-Link, J-Trace and Flasher products. Various targets can be connected to these adapters. The principal types of adapters are active adapters (including measurement, signal smoothing, and power supply functionalities), passive adapters, and needle adapters.
Active Adapters
5V Target Supply Adapter
The 5V Target Supply Adapter provides a supply voltage of 5 V to the target board. It has a standard 20-pin 0.1" socket towards the J-Link or Flasher and a standard 20-pin 0.1" header on the target side and can directly be inserted between the J-Link or Flasher and the debug cable maintaining a 1:1 connection of all debug signals. The supply voltage is fixed to 5 V.
Measurement+Patch Adapter
The Measurement+Patch Adapter provides test points for all debug signals to allow easy access for test probes. It has a standard 20-pin 0.1" socket towards the J-Link or Flasher and a standard 20-pin 0.1" header on the target side and can directly be inserted between the J-Link or Flasher and the debug cable maintaining a 1:1 connection of all debug signals.
Programming Voltage Adapter
The Programming Voltage Adapter delivers two externally provided voltages to the target for programming targets with voltage requirements beyond 5 V. It can directly be inserted between the J-Link and the debug cable maintaining a 1:1 connection of all debug signals.
Signal Smoothing Adapter
The Signal Smoothing Adapter can be inserted between the J-Link or Flasher and the debug target to overcome signal integrity issues. Depending on target load capacitance JTAG signals might be affected by overshoot and ringing. In this case user adjustable series resistors (default 47R) allow for damping critical signal rise/fall times leading to improved signal integrity.
Supply Adapter
The Supply Adapter provides a fixed I/O voltage level for VTRef. It eliminates the need to connect VTRef (pin1) to the target. In general, the target provides its I/O voltage level (VTRef) on pin 1 to the debug probe insuring the debug probe uses the right I/O voltages and avoiding damage of the target debug pins. For increased flexibility the Supply Adapter can adapt to other target voltages in the range from 1.2 V to 5.0 V by replacing a single resistor on the adapter.
Target Supply Adapter
The Target Supply Adapter provides an adjustable supply voltage to the target board. It has a standard 20-pin 0.1" socket towards the J-Link or Flasher and a standard 20-pin 0.1" header on the target side and can directly be inserted between the J-Link or Flasher and the debug cable maintaining a 1:1 connection of all debug signals.
Test Farm Power Adapter
The adapter permits remote control of the power supply of a test device, enabling both power savings and the use of automated reboot for the testing process.
Passive Adapters
2mm Adapter
The 2mm Adapter adapts from the standard 20-pin connector to a 20-pin 2 mm pitch connector. The 2mm Adapter is a 1:1 adapter, since the pinout of the 2 mm pitch connector is identical to the standard 20-pin connector.
50-Mil 10-Pin Patch Adapter
The 50-Mil 10-Pin Patch Adapter adapts from the standard 20 pin 0.1" connector to the standard 10-pin 0.05" Cortex-M connector that is also used on many non-Cortex-M designs but with non-standard pinout. This adapter allows custom connections/wiring between the 20-pin and 10-pin side.
Flying Wire Adapter
The Flying Wire Adapter adapts from the standard 20 pin 0.1" connector to a 10-pin row, allowing to connect J-Link or Flasher to target PCBs via flying wires. It is especially useful when hooking up prototype HW where no final connector is decided yet. Or for manually connecting to ST Discovery boards.
Intel FPGA Adapter
The Intel FPGA Adapter (formerly J-Link Altera Adapter) connects to the 10-pin 100-mil Intel FPGA JTAG connector providing debug access to FPGA based MCU cores like the dual-core ARM Cortex-A9 in the Cyclone V devices.
J-Link Mictor 38 Adapter
The J-Link Mictor 38 Adapter connects to the 38-pin Mictor connector. This adapter connects the GND and JTAG pins to their counterparts on the 20-pin J-Link or Flasher. Trace pins present on the Mictor connector are not connected as they are not present on the 20-pin connector. The 38-pin Mictor side of the adapter can be plugged either directly into the target side or via trace cable.
Microchip 2-Wire JTAG TDI Adapter
The Microchip 2-Wire JTAG TDI Adapter allows debug connections between the J-Link debug probe and target hardware which comes with Microchip IS208x series MCUs. It supports the Microchip 5-pin single row .1" connector.
Microchip Adapter
The Microchip Adapter allows debug connections between J-Link or Flasher and target hardware which comes with Microchip PIC32 series MCUs. It supports the RJ12 modular debug connector as specified by Microchip as well as the 14-pin dual row MIPS debug header and the Microchip 6-pin single row PICkit connector (options, can be soldered by customer on demand).
MIPI-60 Adapter
The MIPI-60 Adapter allows JTAG connections between J-Link, J-Trace or Flasher and Jacinto7 TI target hardware systems. It provides a 19-pin JTAG/SWD and Trace connector, which allows TPIU tracing with up to 4 pins, and an Arm Standard 20-pin connector.
RAFF Adapter
The RAFF Adapter is a Right Angle Female to Female adapter. It is a 1:1 adapter and therefore does not change the pinout and can be used as a replacement of the standard IDC ribbon cable. A compact debug or programming solution can be achieved with a J-Link Compact or Flasher Compact, and the RAFF adapter plugged into a straight / vertical PCB pin header on the target application board.
RX Adapter
The RX Adapter allows connections between J-Link or Flasher and target hardware which comes with the Renesas RX600 / 200 / 100 series MCUs. The RX adapter is able to optionally power the connected target hardware. 3.3 V or 5 V supply voltage can be selected using a Jumper. The target is supplied via the VTref connection when the supply option is jumpered.
SiFive-ARTY Adapter
The SiFive-ARTY Adapter allows debug connections between the J-Link and the ARTY board running SiFive RISC-V core bitstreams. The ARTY board provides several identical headers where the JD header is used as the debug connector, when running SiFive RISC-V bitstreams on the ARTY board.
SiLabs C2 Adapter
The SiLabs C2 Adapter allows debug connections between J-Link or Flasher and target hardware which comes with Silicon Labs C2 debug interface. It adapts from the 20-pin 0.1'' standard debug connector to a 10-pin 0.1'' connector with a pinout compatible with Silicon Labs eval boards.
Xilinx Adapter
The Xilinx Adapter connects to the 14-pin 2 mm Xilinx JTAG connector providing debug access to FPGA-based MCU cores like the Arm Cortex-A9 core in the Zynq devices.
Needle Adapters
6-Pin Needle Adapter
The 6-Pin Needle Adapter has been designed to connect a J-Link or Flasher to a PCB which does not come with a mating connector or programming header. The designed pattern with 3 locating pins ensures, that the adapter can only be connected in one way. The 6-Pin Needle Adapter allows manufacturers to save costs and space on their PCBs since there is no need to provide the PCB with additional connectors. It adapts from the 20-pin 0.1'' JTAG to a 6-pin needle connector.
10-Pin Needle Adapter
The10-Pin Needle Adapter has been designed to connect a J-Link or Flasher to a PCB which does not come with a mating connector or programming header. The designed pattern with 3 locating pins ensures that the adapter cannot be connected the wrong way. The needle adapter allows manufacturers to save costs and space on their PCBs since there is no need to provide the PCB with additional connectors. It adapts from the 20-pin 0.1'' JTAG to a 10-pin needle connector.
