STMicroelectronics EVLIOL4LSV1

Overview

EVLIOL4LSV1 from STMicroelectronics is an IO-Link Class-A actuator evaluation board for industrial tower lights and alarm indicators, integrating the L6364Q dual-channel IO-Link transceiver, STM32G071CBT6 Arm Cortex-M0+ MCU (128 KB Flash), and IPS4260L quad intelligent low-side switch. It delivers up to 1 A per channel (2 A total) at 18–30 V DC, supports COM3 (230.4 kbps), and includes open-load detection and TVS surge protection (SMBJ30CA).

For engineers reviewing the EVLIOL4LSV1 datasheet, EVLIOL4LSV1 pinout, EVLIOL4LSV1 application, or EVLIOL4LSV1 equivalent, this board serves as a production-ready reference design for smart indicator systems requiring IO-Link diagnostics, load monitoring, and industrial-grade ESD/surge resilience in factory automation environments.

Technical Context

The board implements a full IO-Link device stack on the STM32G071CBT6 MCU, interfacing with an IO-Link master via the L6364Q transceiver in SIO/COM3 mode. The L6364Q handles physical layer signaling, wake-up detection, and cyclic data exchange while supporting both point-to-point and multi-drop configurations.

All four output channels are driven by the IPS4260L, which provides current limiting, thermal shutdown, and open-load diagnosis per channel. The M12 4-pin connector complies with IEC 61131-9, and the dedicated SWD 5-pin header enables firmware programming and debug without disrupting IO-Link operation.

FAQ

What IO-Link communication speed does EVLIOL4LSV1 support?

EVLIOL4LSV1 supports IO-Link COM3 at 230.4 kbps, the highest standard speed for Class-A devices. This enables fast parameter read/write cycles and real-time process data transfer between the master and the actuator, essential for dynamic lighting control and alarm state updates in time-critical factory environments.

Does EVLIOL4LSV1 include built-in diagnostics for connected loads?

Yes - each of the four IPS4260L low-side switches provides hardware-level open-load detection. When enabled, it reports load disconnection or LED failure via the IO-Link process data stream, allowing the master controller to trigger maintenance alerts without external sensing circuitry.

Can EVLIOL4LSV1 be used with non-ST IO-Link masters?

Yes - EVLIOL4LSV1 complies fully with IEC 61131-9 and uses a standardized IODD file for device description. It has been validated with third-party IO-Link masters from ifm, Pepperl+Fuchs, and Balluff, ensuring interoperability across vendor ecosystems in mixed-automation deployments.

What is the role of the SWD 5-pin connector on EVLIOL4LSV1?

The SWD 5-pin connector provides direct access to the STM32G071CBT6's Serial Wire Debug interface. It allows firmware flashing, real-time debugging, and register inspection without interrupting IO-Link communication or requiring additional adapters - critical for field firmware updates and validation during commissioning.
