Versatile microcontroller debugger and programmer supporting a range of target interfaces (JTAG, SWD, SWIM, ICC, ...)

RLink is a versatile, high-performance solution for connecting to 32-bit and 8-bit microcontrollers to program the target device and debug application code.

RLink connects to application, or evaluation boards via JTAG, SWD for ARM Cotex M-baseed microcotnrollers. Is supports STMicroelectronics' SWIM protocol for STM8, and ICC protocol for ST7.*

* Note: ST72C variants are not supported.

RLink is driven by the Ride7 integrated development environment for debugging and programming of microcontroller applications. With the RFlasher programming software, it also provides a very-low cost programming solution for laboratory and production environments.


STX-RLINK is the STMicroelectronics' part number for the Raisonance RLink-STD or "Standard". The two products are technically identical, support the same range of microcontrollers and the same performance characteristics using the same software packages.

Raisonance RLink was previously sold by STMicroelectronics as STX-RLINK. ST has stopped selling STX-RLINK, however the RLink is still available from Digi-Key and other Raisonance tool distributors.

In addition to the STM32 and STM8 microcontroller families, RLink supports legacy microcontrollers that are not supprorted by other programmer/debuggers such as the ST7, STR7 and STR9 families.


RLink is supported by the Ride7 software development environment and Raisonance RKit-ARM* and RKit-STM8 (STM8 / ST7)* software. 

Download Ride7 and associated RKits from the Raisonance support web site.

Note* : Code size limitations apply when using these software with RLink. Please refer to the user documentation for further details.
