- Combine full J-Link debugging capabilities with high-speed streaming trace
Key features
Real-time instruction trace
Captures every executed instruction non-intrusively in real time, which enables developers to pinpoint hard-to-find issues and thoroughly understand program flow.
Live code coverage and profiling
Tracks executed code and measures performance in real time, supporting optimization of applications and revealing untested or inefficient sections.
Same licenses and features as J‑Trace Pro
Comes with the full set of J‑Link Pro licenses and capabilities, ensuring seamless debugging and compatibility across a wide range of microcontrollers and development environments.
J-Trace models
All SEGGER J-Trace models share the same advanced feature set and tool compatibility. The key difference between models lies in the type of devices and architectures they support. From multi-architecture solutions to specialized models for Arm Cortex-M, Cortex-A/R/M, and RISC-V, each J-Trace provides the same professional performance and reliability tailored to specific target families.
A detailed overview of all models and their specifications is available in a comprehensive comparison table.
J-Trace PRO
The multi-architecture trace probe
The J-Trace PRO is SEGGER's "all-in-one" streaming trace probe for any CPU core and architecture.
J-Trace PRO Cortex-A/R/M
The Arm Cortex trace probe
The J-Trace PRO for Cortex-A/R/M-based microcontrollers supports tracing on a wide range of Arm Cortex cores.
J-Trace PRO Cortex-M
The leading trace probe
The J-Trace PRO for Cortex-M-based microcontrollers enables continuous streaming trace for code development and optimization.
J-Trace PRO RISC-V

Debug and trace connectors
J-Trace has two connectors. The pinout of the debug and trace connector is in the SEGGER knowledge base. The debug connector is for debug only and can be used with target adapters for J-Link.
Please note that only one connector can be used at a time.
Supported devices
The list of supported manufacturers, families, devices, and SoCs includes tens of thousands of devices in hundreds of device families.

[1] The download speeds listed here are the peak download speeds that can be achieved by the particular J-Trace model. The actual download speed may be lower as it depends on various factors, such as, but not limited to: The selected debug interface & speed, the CPU core and its operating frequency, other devices in the JTAG chain in case JTAG is used as target interface.
[2] Unlimited streaming trace allows to transmit trace in real time to the PC. While traditional trace only allows to see and analyze the last xxx MB of trace data, with streaming trace it is possible to have all data available. This allows extended debugging features, such as code coverage or CPU load analysis based on a function basis.
