Supported devices
SEGGER Debug and Trace Probes support a wide range of CPUs and architectures.
The list is always valid for the latest version (highest version number) of the software. This may be a release (even version number) or a beta version (odd version number) since support for some devices is usually added in a beta phase first.
Note that a device may still be supported even if it is not on the list. Device not listed? Please don’t hesitate to contact us.

1 The download speeds listed here are the peak download speeds that can be achieved by the particular J-Link 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.
4 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 like code coverage, CPU load analysis based on a function basis, ...
5 Max. sampling frequency is guaranteed for sampling one variable and for appropriate target interface speeds being selected (min. 1 MHz). Sampling more than one variable in parallel, may lead to a smaller max. sampling frequency. When this threshold of sampling frequency decrease is hit, depends on different factors (Number of variables to be sampled in parallel, size of each variable, selected target interface speed, ...)
6 Only limited by the bandwidth of the debug interface. Typical sampling frequency of one variable: > 10 kHz.
