STMicroelectronics STELLARLINK In-Circuit Debugger/Programmer is a cost-effective, small-size, and fast-prototyping solution for vehicle applications. This programmer is a passive USB-to-JTAG debugger and the programmer dongle that supports Stellar MCUs, SR5, SR6, and SPC5 microcontrollers. The STELLARLINK features a short development time through easy-to-use hardware and software fully integrated into StellarStudio and SPC5-STUDIO IDEs. This STELLARLINK also features a virtual COM port interface enabling the host PC to communicate with the microcontroller through a UART.
