Silicon Labs EFR32xG23
Contents
The EFR32xG23 device family from Silicon Labs are Cortex-M33 based microcontrollers.
On-Chip Memory Regions
The EFR32xG23 series devices have an internal flash of up to 512 KiB size and a user data page (UDP) of 1 KiB. J-Link supports flash programming for both the internal flash and UDP.

Tracing on EFR32ZG23xxx series
This section describes how to get started with trace on the SiLabs EFR32ZG23xxx MCUs. This section assumes that there is already a basic knowledge about trace in general (what is trace, what different implementations of trace are there, etc.). If this is not the case, we recommend to read Trace chapter in the J-Link User Manual (UM08001).
Note:
- The sample projects come with a pre-configured project file for Ozone that runs out-of-the box.
- The following sample project is designed to be used with J-Trace PRO for streaming trace, J-Link Plus for buffer tracing (TMC/ETB trace) and Ozone to demonstrate streaming trace.
- In order to rebuild the sample project, SEGGER Embedded Studio can be used.
- All examples are shipped with a compiled .JLinkScriptfile (.pex), should you need the original source, please get in touch with SEGGER directly via our support system: https://www.segger.com/ticket/.
Tracing on SiLabs EFR32ZG23xxx
Minimum requirements
In order to use trace on the ST EFR32ZG23xxx MCU devices, the following minimum requirements have to be met:
- J-Link software version V7.88h or later
- Ozone V3.30 or later (if streaming trace and / or the sample project from below shall be used)
- J-Trace PRO for Cortex-M HW version V1.0 or later for streaming trace
To rebuild the project our IDE Embedded Studio can be used. The recommended version to rebuild the projects is V6.30. But the examples are all prebuild and work out-of-the box with Ozone, so rebuilding is not necessary.
Streaming trace
The project has been tested with the minimum requirements mentioned above and a SiLabs BRD4204C Rev 00 Board on a PCB4001 Rev 03 motherboard.
