Product details

Overview

ST-LINK/V2-ISOL from STMicroelectronics is an isolated in-circuit debugger and programmer for STM8 and STM32 microcontrollers, featuring 1000 Vrms digital isolation between PC and target board, USB 2.0 full-speed interface, and dual-mode SWIM (1.65–5.5 V) and JTAG/SWD (1.65–3.6 V, 5 V tolerant) support for embedded firmware development and programming.

For engineers reviewing the ST-LINK/V2-ISOL datasheet, ST-LINK/V2-ISOL pinout, ST-LINK/V2-ISOL application, or ST-LINK/V2-ISOL equivalent, key selection criteria include isolation voltage rating, supported debug protocols (SWIM/JTAG/SWD), host OS compatibility (Windows/Linux/macOS), and firmware update capability via DFU mode.

Technical Context

The ST-LINK/V2-ISOL implements galvanic isolation using integrated digital isolators to separate USB-side logic from target-side debug signals, enabling safe debugging of high-voltage or floating-ground applications. It embeds an STM32F103C8T6 microcontroller running proprietary ST-LINK firmware that handles protocol translation between USB and SWIM/JTAG/SWD physical layers.

It supports both low- and high-speed SWIM programming (9.7 kB/s and 12.8 kB/s respectively) and enables Serial Wire Viewer (SWV) trace streaming over SWD. The device operates across 0 °C to 50 °C and draws power solely from the USB port (5 V).

Key Specifications

Parameter	Value and Actual Design Meaning
Isolation Voltage	1000 Vrms - enables safe debugging of mains-referenced or high-side power systems without ground loop risk
USB Interface	USB 2.0 full-speed (12 Mbps) - ensures reliable host communication with standard USB-A to Mini-B cable
SWIM Voltage Range	1.65 V to 5.5 V - supports programming all STM8 devices regardless of core supply voltage
JTAG/SWD Voltage Range	1.65 V to 3.6 V with 5 V tolerant inputs - compatible with diverse STM32 I/O voltage domains
Programming Speed (SWIM)	9.7 kB/s (low-speed), 12.8 kB/s (high-speed) - reduces firmware flash time during iterative development
Operating Temperature	0 °C to 50 °C - validated for use in industrial bench environments and production test fixtures
Firmware Update	Direct firmware update (DFU) mode - allows field upgrades without external tools or hardware changes

FAQ

Does ST-LINK/V2-ISOL support SWV trace streaming?

Yes, ST-LINK/V2-ISOL supports Serial Wire Viewer (SWV) communication over the SWD interface. This enables real-time trace data capture-including ITM stimulus ports and DWT event counters-for runtime analysis in STM32CubeIDE and other compatible IDEs without requiring additional hardware probes.

Can ST-LINK/V2-ISOL program both STM8 and STM32 devices?

Yes, it natively supports both families: SWIM protocol for STM8 (1.65–5.5 V) and JTAG/SWD for STM32 (1.65–3.6 V). No configuration switch or firmware change is required-the host software (e.g., STM32CubeProgrammer or STVP) automatically selects the correct protocol based on target identification.

What isolation technology does ST-LINK/V2-ISOL use?

ST-LINK/V2-ISOL uses integrated digital isolators-ST's proprietary silicon-based isolation-between the USB controller side and the debug signal side. This provides reinforced 1000 Vrms isolation per IEC 60747-17, eliminating ground loops and protecting host PCs during high-voltage target debugging.

Is a separate power supply needed for ST-LINK/V2-ISOL?

No, ST-LINK/V2-ISOL is bus-powered exclusively via its USB Type-A to Mini-B cable. It draws ≤500 mA at 5 V and supplies no output power to the target-target power must be provided separately. The isolation barrier prevents any current path between USB VBUS and target VDD.
