STMicroelectronics P-NUCLEO-IOD04A1

Overview

P-NUCLEO-IOD04A1 from STMicroelectronics is an STM32 Nucleo pack for IO-Link device applications based on the L6364Q transceiver, IPS4140HQ quad-channel high-side switch, and STM32G071RB or STM32L073RZ microcontrollers. It enables industrial sensor/actuator node prototyping with full IO-Link V1.1.3 communication, real-time digital output control, and IODD file support for master integration.

For engineers reviewing the P-NUCLEO-IOD04A1 datasheet, P-NUCLEO-IOD04A1 pinout, P-NUCLEO-IOD04A1 application, or P-NUCLEO-IOD04A1 equivalent, this kit delivers validated firmware stack, transceiver + power switch drivers, IDE compatibility (IAR/KEIL/STM32CubeIDE), and hardware abstraction for rapid IO-Link device development in industrial automation environments.

Technical Context

This kit integrates STM32Cube HAL-based middleware to implement an IO-Link device mini-stack compliant with IEC 61131-9, supporting COM1 (4.8 kbaud), COM2 (38.4 kbaud), and COM3 (230.4 kbaud) modes via the L6364Q transceiver. It provides full register-level access to L6364Q configuration and diagnostics.

The firmware includes production-ready drivers for the IPS4140HQ quad high-side switch - supporting independent channel enable/disable, overcurrent detection, thermal shutdown reporting, and configurable current limiting - all abstracted through standardized BSP APIs aligned with STM32Cube expansion architecture.

FAQ

What MCU variants are supported on the P-NUCLEO-IOD04A1 board?

The P-NUCLEO-IOD04A1 supports two MCU options: STM32G071RB (64 MHz Cortex-M0+, 128 KB Flash) and STM32L073RZ (32 MHz Cortex-M0+, 192 KB Flash). Both are pre-soldered on separate board variants and fully supported by the included FP-IND-IODOUT1 function pack firmware and BSP layer.

Does the kit include hardware for IO-Link master connection?

No - P-NUCLEO-IOD04A1 is an IO-Link *device* evaluation kit only. It requires connection to an external IO-Link master (e.g., via STEVAL-IOD003V1 or X-NUCLEO-IOD02A1) using standard M12 3-wire cabling. The L6364Q transceiver handles physical layer compliance, but no master-side hardware is included.

Is the IODD file provided in editable format?

Yes - the FP-IND-IODOUT1 package includes the IODD (IO-Link Device Description) file in XML format compliant with IEC 61131-9 Annex D. It is preconfigured for the IPS4140HQ output channels and L6364Q diagnostics, and can be modified using ST's IODD Editor tool before uploading to the master.

Can this kit control both high-side and low-side switches simultaneously?

No - P-NUCLEO-IOD04A1 integrates only the IPS4140HQ quad high-side switch. While the FP-IND-IODOUT1 function pack also supports IPS4260LM (low-side) and IPS2050H variants, those require different Nucleo packs (P-NUCLEO-IOD5A1 and P-NUCLEO-IOD3A1 respectively); hardware-level switching between topologies is not supported on this board.
