STMicroelectronics P-NUCLEO-IOM01M1

Overview

P-NUCLEO-IOM01M1 from STMicroelectronics is an IO-Link master evaluation kit comprising the STEVAL-IOM001V1 (L6360-based IO-Link PHY) and NUCLEO-F446RE (STM32F446RET6 MCU, 180 MHz, 512 KB Flash). It implements IO-Link v1.1 stack licensed from TEConcept GmbH (10k-minute renewable license), supports I²C/UART/SPI interfaces, and operates from 18–32.5 V for industrial sensor connectivity.

For engineers reviewing the P-NUCLEO-IOM01M1 datasheet, P-NUCLEO-IOM01M1 pinout, P-NUCLEO-IOM01M1 application, or P-NUCLEO-IOM01M1 equivalent, this kit enables rapid validation of IO-Link master functionality, L6360 PHY robustness, SPI-based low-level access, and integration with STM32-based gateways or PLC edge nodes.

Technical Context

The kit integrates two functionally distinct boards: STEVAL-IOM001V1 provides full IO-Link physical layer compliance (IEC 61131-9), including CQ/L+ switching, IQ digital input, overload/overtemperature protection with non-dissipative cut-off, and EMC certification per IEC61000-4-2/3/5. It uses the L6360 transceiver in QFN-26L (3.5×5×1 mm) package with 3.3 V/5.0 V selectable 65 mA linear regulator.

The NUCLEO-F446RE board hosts the STM32F446RET6 ARM Cortex-M4 MCU (180 MHz, 512 KB Flash, 128+4 KB RAM), delivers IO-Link stack execution, exposes Arduino UNO R3 and ST Morpho headers, and includes on-board ST-LINK/V2-1 debugger. Communication between MCU and PHY occurs via SPI (slave mode), I²C, or UART - enabling both GUI-driven evaluation (IO-Link Control Tool©) and embedded firmware integration.

FAQ

Is the IO-Link stack pre-loaded and field-upgradable?

Yes. The NUCLEO-F446RE board ships with the TEConcept GmbH IO-Link v1.1 stack pre-flashed (10k-minute renewable license). Updates are supported exclusively via the procedure in UM2421; unauthorized erasure or overwrite permanently disables stack recovery.

What interfaces connect the MCU and L6360 PHY?

The NUCLEO-F446RE communicates with the STEVAL-IOM001V1's L6360 via SPI (configured as slave), I²C, or UART. SPI is used for low-level master access in the provided demo application; I²C and UART support diagnostics and configuration.

Can multiple P-NUCLEO-IOM01M1 units be combined into a multi-port master?

Yes. The design supports up to four STEVAL-IOM001V1 boards per NUCLEO-F446RE using ST Morpho connectors, enabling quad-port IO-Link master configurations for evaluating multi-sensor networks or distributed I/O systems.

Does the kit include software tools and source code?

Yes. ST provides the IO-Link Control Tool© GUI (TEConcept property) for interactive evaluation, plus the Low-Level IO-Link Master Access Demo Application source code and API specification - all freely available on www.st.com under UM2421 and related documentation.
