J-Link Adapters

The following adapters are available for J-Link:

•

J-Link JTAG Isolator

The J-Link JTAG Isolator can be connected between J-Link and any ARM-board that uses the standard 20-pin JTAG-ARM connector to provide

electrical isolation. This is essential when the development tools are not connected to the same ground as the application. It is also useful to

protect the development tools from electrical spikes that often occur in some applications, such as motor control applications. Another

typical field of application is development of products with sensors or other analog circuitry, in which case the target hardware is protected

from electrical noise originating from the development PC.

The J-Link JTAG Isolator is compatible with , , , and .

J-Link SWD Isolator

The J-Link SWD Isolator can be connected between and any ARM-board that uses the standard 20-pin 0.1" male connector to provide

electrical isolation. This is essential when the development tools are not connected to the same ground as the application. It is also useful to

protect the development tools from electrical spikes that often occur in some applications, such as motor control applications. Another

typical field of application is development of products with sensors or other analog circuitry, in which case the target hardware is protected

from electrical noise originating from the development PC.

The J-Link SWD Isolator is compatible with , , , and .

J-Link Supply Adapter

The J-Link 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. If signal VTRef is not desired on the target board it can be omitted by using the J-Link Supply

Adapter, manually setting the I/O voltage. Default I/O voltage is 3.3 V. For increased flexibility the J-Link 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.

The Supply Adapter can be inserted between J-Link and the target maintaining a 1:1 connection of all debug signals (except VTRef/pin 1). It

has a standard 20-pin 0.1" socket towards the J-Link debug probe and a standard 20-pin 0.1" header on the target side. The main reason

for using the adapter is to reduce the number of connections to the target, especially in production environments. It can also be used with

Flasher ARM. For dual wire debug interfaces such as SWD, typically only 3 wires are still required: SWDIO and SWDCLK as well as GND. For

single wire interfaces such as SPD, the number of connections is reduced to 2 accordingly.

The J-Link Supply Adapter is compatible with , , , and .

J-Link RX FINE Adapter

The J-Link RX FINE Adapter allows connections between J-Link and Renesas RX based target hardware that supports the Renesas

FINE interface (RX63xx, RX2xx, RX1xx CPUs).

J-Link 19-pin Cortex-M Adapter

The J-Link 19-pin Cortex-M Adapter allows JTAG, SWD and SWO connections between J-Link and Cortex-M based target hardware systems.

It adapts from the 20-pin 0.1'' JTAG connector to a 19-pin 0.05'' Samtec FTSH connector as defined by ARM.

The J-Link 19-pin Cortex-M Adapter may also be used to connect J-Link to a non Cortex-M target as far as the target connector uses the

same pinout as shown below.

By default, TRST is not connected, but the Cortex-M Adapter comes with a solder bridge (NR1) which allows TRST to be connected to pin 9

of the Cortex-M adapter.

J-Link 9-pin Cortex-M Adapter

The J-Link 9-pin Cortex-M Adapter allows JTAG, SWD and SWO connections between J-Link and Cortex-M based target hardware systems. It

adapts from the 20-pin 0.1'' JTAG connector to a 9-pin 0.05'' Samtec FTSH connector as defined by ARM.

The J-Link 9-pin Cortex-M Adapter may also be used to connect J-Link to a non Cortex-M target as far as the target connector uses the same

pinout as shown below.

By default, TRST is not connected, but the Cortex-M Adapter comes with a solder bridge (NR1) which allows TRST to be connected to pin 9

of the Cortex-M adapter.

J-Link 2mm Adapter

The J-Link 2mm Adapter adapts from the standard 20-pin J-Link connector to a 20-pin 2mm-pitch connector. The J-Link 2mm Adapter is a

1:1 adapter, since the pinout of the 2mm pitch connector is identical to the standard 20-pin J-Link connector.

Pins 14, 16, 18, 20:

On some models like the high-end model J-Link

PRO, these pins may not be connected to GND

but are reserved for future use/extension. In

case of doubt, leave open on target hardware.

J-Link Altera Adapter

The J-Link Altera Adapter connects to the 10 pin Altera JTAG connector providing debug access to FPGA based MCU cores like the dual-core

ARM Cortex-A9 in the Cyclone V devices.

J-Link ARM-14 Adapter

This adapter allows to use J-Link with ARM7/9/11 targets using this 14-pin 0.1" mating JTAG connector defined by ARM.

The 14-pin connector, though defined by ARM as an alternative to the 20-pin connector is not widely used on modern eval boards.

J-Link Measurement+Patch Adapter

The J-Link 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 debug probe and a standard 20-pin 0.1" header on the target side and can directly be inserted between

the J-Link and the debug cable maintaining a 1:1 connection of all debug signals. For increased flexibility VTref on pin 1 and the target

supply voltage on pin 19 can be interrupted by means of two jumpers.

The J-Link Measurement+Patch Adapter allows easy customized wiring between J-Link and targets that do not provide a standard debug

connector that fits to any of the adapters available for J-Link (e.g. the Discovery Boards from ST Microelectronics). The wiring between J-

Link and the target is done via colored jumper wires that are shipped with the J-Link Measurement+Patch Adapter.

J-Link Microchip Adapter

The J-Link Microchip Adapter allows debug connections between J-Link 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).

J-Link Mictor 38 Adapter

The J-Link Mictor 38 Adapter connects to the 38 pin Mictor connector. The pin out follows the single target connector pinout specification as

defined in the ARM "ETM Architecture Specification".

The adapter connects the GND and JTAG pins to their counterparts on the 20-pin J-Link. Trace pins present on the Mictor connector are not

connected as they are not present on the 20-pin J-Link connector. The 38-pin Mictor side of the adapter can be plugged either directly into

the target side or via trace cable. The J-Link side connects to J-Link via 20-pin flat cable.

If you need trace capability, take a look at the and Debug + Trace Probes.

The J-Link PPC 14 pin Adapter allows JTAG connections between J-Link and target hardware which use an MCU with Power Architecture or

PowerPC. It adapts from the 20-pin 0.1'' to a 14-pin 0.1'' JTAG connector.

Note: J-Link support for PowerPC is not yet available.

J-Link Signal Smoothing Adapter

The J-Link Signal Smoothing Adapter can be inserted between the J-Link debug probe 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.
