Product details
Overview
STX-RLINK from Raisonance is an in-circuit debugger and programmer supporting STM8, ST7, STM32, STR7, and STR9 microcontrollers via SWIM, ICC, JTAG, and SWD interfaces. It connects to target boards using 4-pin SWIM (STM8), 10-pin ICC (ST7), or 20-pin JTAG-SWD (ARM-based MCUs), draws power from USB, and enables unlimited debugging for STM8/ST7 and Flash-limited debugging for ARM cores (≤64 KB Flash: up to 32 KB debug code; >64 KB Flash: up to 64 KB).
For engineers reviewing the STX-RLINK datasheet, STX-RLINK pinout, STX-RLINK application, or STX-RLINK equivalent, this tool serves as a low-cost, protocol-flexible hardware interface for embedded firmware development, flash programming, and real-time debugging across five ST MCU families - with direct integration into Ride7 IDE and RFlasher7 software.
Technical Context
The STX-RLINK implements four distinct physical debug protocols: SWIM for STM8 (single-wire), ICC for ST7 (5-wire), and JTAG/SWD for ARM-based devices (STM32/STR7/STR9). It operates exclusively as a host-controlled bridge - no on-board trace logic or ETM support - and relies on external PC software (Ride7, RFlasher7, STVD) for command translation and memory access.
Debug session behavior is architecture-dependent: STM8/ST7 support full, unlimited in-circuit debugging; for STM32/STR7/STR9, debug code size is capped at half the Flash size (if ≤64 KB) or fixed at 64 KB (if >64 KB), reflecting hardware-assisted breakpoint and watchpoint constraints in the underlying debug interface implementation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supported Protocols | SWIM (STM8), ICC (ST7), JTAG & SWD (STM32/STR7/STR9) - enables single-hardware compatibility across five MCU families without protocol adapter swaps. |
| Host Interface | USB 2.0 Full-Speed - provides plug-and-play connectivity, bus-powered operation, and eliminates need for external power supplies or serial/parallel adapters. |
| Target Power | Powered from USB only - does not supply voltage to target board; requires target to be self-powered or externally powered during debug sessions. |
| Debug Code Limit (ARM) | ≤64 KB Flash: max 32 KB debug code; >64 KB Flash: max 64 KB - constrains executable debug image size, affecting complex breakpoint/watchpoint usage in large applications. |
| Software Integration | Ride7 IDE (full project control), RFlasher7 (mass programming), STVD/STVP (legacy ST tools) - ensures interoperability with both vendor-agnostic and ST-specific workflows. |
| Adapter Interfaces | 4-pin SWIM header, 10-pin ICC header, 20-pin JTAG-SWD header - physically distinct connectors prevent misconnection and enforce correct protocol selection per target MCU. |
Availability
STX-RLINK is available at Aetrix Electronics and suitable for embedded firmware development, production programming, and university-level MCU education requiring stable component supply and cross-family debug consistency.
Supply support for STX-RLINK includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.
Manufacturer
Raisonance is a France-based embedded tools developer specializing in integrated development environments, compilers, and debug hardware for 8-bit and 32-bit microcontrollers since 1991.
The RLink product line - including STX-RLINK - was designed to deliver low-cost, multi-protocol in-circuit debugging and programming for ST's legacy and mainstream MCU portfolios, prioritizing IDE interoperability and field-deployable simplicity over advanced trace capabilities.
FAQ
Does STX-RLINK support trace functionality for STR9 or STM32 devices?
No. The STX-RLINK does not include Embedded Trace Macrocell (ETM) or trace port support. It provides only core debug features - breakpoints, watchpoints, register/memory read/write, and flash programming - for all supported MCUs. Trace-capable debugging requires separate high-end tools like ST-LINK/V2-1 with SWV or third-party trace probes.
Can STX-RLINK program STM8L or STM32L ultra-low-power devices?
Yes - if the device belongs to the officially supported families (STM8, STM32, STR7, STR9, ST7) and uses standard SWIM or SWD signaling. STM8L and STM32L series are covered under STM8 and STM32 support respectively, provided they implement the required debug interface and are listed in Raisonance's compatible device database.
Is STX-RLINK compatible with modern Windows 10/11 or Linux hosts?
Yes. Raisonance provides signed USB drivers for Windows 10/11 (x64) and native Linux binaries for RFlasher7 and command-line utilities. Ride7 IDE runs on Windows; Linux/macOS users can use RFlasher7 for programming and open-source GDB+OpenOCD alternatives for debugging where SWD is supported.
What is the difference between STX-RLINK and ST-LINK/V2?
STX-RLINK is a multi-protocol, multi-vendor (ST-focused) debug probe with SWIM/ICC/JTAG/SWD support and Ride7 IDE integration; ST-LINK/V2 is ST's proprietary SWD-only probe, tightly coupled with STM32CubeIDE and limited to STM32 devices. STX-RLINK supports broader legacy coverage (ST7, STR9) but lacks ST's official CMSIS-DAP compliance and mass-production certification.
