STMicroelectronics P-NUCLEO-IOD7A1

Overview

P-NUCLEO-IOD7A1 from STMicroelectronics is an STM32 Nucleo evaluation and development pack integrating the X-NUCLEO-IOD02A1 (L6364Q dual-channel IO-Link/SIO transceiver), X-NUCLEO-OUT07A1 (IPS4260LM quad low-side intelligent power switch), and NUCLEO-G071RB (STM32G071RB Arm® Cortex®-M0+ MCU, 64 MHz, 128 KB Flash, 36 KB SRAM) for industrial IO-Link device and digital output module prototyping.

For engineers reviewing the P-NUCLEO-IOD7A1 datasheet, P-NUCLEO-IOD7A1 pinout, P-NUCLEO-IOD7A1 application, or P-NUCLEO-IOD7A1 equivalent, this kit supports rapid validation of IO-Link sensor/actuator node firmware, SIO compatibility, real-time load diagnostics, and industrial-grade digital output control with integrated protection and stack-level interoperability via FP-IND-IODOUT1.

Technical Context

The P-NUCLEO-IOD7A1 implements a complete IO-Link device node architecture: the L6364Q provides physical layer compliance with IEC 61131-9 (COM1/COM2/COM3 modes), bidirectional serial communication, and integrated V_CC/V_PORT regulation; the IPS4260LM delivers per-channel current limiting (0.5 A continuous, 2 A peak), thermal shutdown, and open-load detection across four independent low-side switches.

The STM32G071RB hosts the FP-IND-IODOUT1 function pack - combining the X-CUBE-IOD02-derived IO-Link demo stack and X-CUBE-IPS control middleware - enabling concurrent management of transceiver configuration, IODD parsing, channel state reporting, and diagnostic event handling over USB CDC or UART.

FAQ

Does P-NUCLEO-IOD7A1 support IO-Link master functionality?

No. The P-NUCLEO-IOD7A1 implements only IO-Link device (slave) functionality via the L6364Q transceiver and FP-IND-IODOUT1 stack. It connects to an external IO-Link master and does not provide master-side protocol handling, cyclic data arbitration, or parameter server services.

Can the IPS4260LM channels drive inductive loads such as solenoids or relays?

Yes. Each IPS4260LM channel supports inductive loads up to 2 A peak with built-in flyback energy clamping, overcurrent protection, and thermal shutdown. The board includes snubber networks and layout-optimized traces to manage voltage spikes during turn-off.

Is the FP-IND-IODOUT1 function pack preloaded on the NUCLEO-G071RB?

No. The board ships with a basic blinky example. Users must download and flash FP-IND-IODOUT1 from ST's official website (st.com) using STM32CubeIDE or ST-Link CLI tools. The pack includes source code, IODD examples, and documentation for custom node implementation.

What is the maximum cable length supported between P-NUCLEO-IOD7A1 and an IO-Link master?

Up to 20 meters, compliant with IEC 61131-9 Class A requirements. Performance depends on cable quality (shielded twisted pair, AWG ≤24), noise environment, and selected COM mode - COM3 (230.4 kbps) is limited to ~10 m, while COM1 (4.8 kbps) achieves full 20 m with robust error recovery.
