SEGGER Microcontroller J-Trace The SEGGER Microcontroller KG J-Trace is an isolator. It can be connected between a J-Trace Pro V2 or any ARM-board that uses the standard 19-pin Cortex-M connector to provide electrical isolation while keeping high-speed peed trace capabilities. This is essential when the development tools are not connected to the same ground. It is useful to protect the development tools from electrical spikes that often occur in some applications. Features and Benefits: • 1 kV DC isolation
• 3 LEDs to indicate emulator power, target power and target RESET
• ETM trace pins fully supported up to 75MHz trace clock
• JTAG frequency: up to 50MHz
• JTAG standard 19-pin connection supporting TDI, TMS, TCK, TDO, RESET and SWD/SWO signals
• Powered from an emulator, a few microamps (<25μA) drawn from a target
• SWD frequency: up to 4MHz
