Product details
Overview
STEVAL-FSM01M1 from STMicroelectronics is a dual-channel digital I/O expansion board designed for safe automation, featuring galvanic isolation (1 kVRMS), IEC 61131-2 Type 1/3 compliant inputs, and two high-side switch outputs rated at 0.5 A (OUT1) and 2 A (OUT2). It integrates IPS160HF and IPS161HF intelligent power switches, CLT03-2Q3 self-powered dual-input current limiter, STISO621 100 Mbps digital isolator, L7983/LDK220 power management, and ADC120 12-bit/1 Msps analog-to-digital converter - all optimized for industrial PLC applications.
For engineers reviewing the STEVAL-FSM01M1 datasheet, STEVAL-FSM01M1 pinout, STEVAL-FSM01M1 application, or STEVAL-FSM01M1 equivalent, this board supports runtime-controlled diagnostics, real-time condition monitoring via SPI, active test-pulse generation for input integrity verification, and cascade high-side switch topology for functional safety compliance in factory automation systems.
Technical Context
The board implements a split-domain architecture: logic side (3.3 V, STM32 Nucleo-compatible via ST Morpho headers CN7/CN10) is galvanically isolated from process side (8–60 V) using STISO621 dual-channel isolators. Digital I/O translation occurs across isolation barrier with dedicated diagnostic feedback paths for each channel.
Input section uses CLT03-2Q3 to provide native test-pulse generation and self-powered operation up to 60 V; output section combines STL42P6LLF6 P-channel MOSFETs with IPS160HF/IPS161HF high-side switches to deliver redundant overcurrent/overtemperature protection, fast demagnetization, and configurable cut-off limitation - enabling safe switching of inductive loads in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Voltage Range | 8–30 V standard, extendable to 60 V - enables compatibility with wide industrial supply rails including 24 V DC and 48 V DC systems. |
| Digital Input Compliance | IEC 61131-2 Type 1 and Type 3 - ensures interoperability with standard PLC field sensors and industrial binary signal sources. |
| Output Current Rating | OUT1: 0.5 A; OUT2: 2 A - supports mixed-load configurations such as status indicators (low-current) and solenoids/valves (high-current). |
| Galvanic Isolation | 1 kVRMS - provides reinforced insulation between logic and process domains, meeting safety requirements for industrial control equipment. |
| Analog Monitoring Capability | ADC120 12-bit/1 Msps with 8-channel SPI interface - enables real-time voltage sensing of VCC, OUT1, OUT2, and internal rail nodes for predictive diagnostics. |
| Isolation Data Rate | 100 Mbps (STISO621) - supports high-speed bidirectional communication across isolation barrier without timing bottlenecks. |
| Power Management | L7983 (60 V buck) + LDK220 (low-noise LDO) - delivers stable 3.3 V logic supply with low ripple and high PSRR for noise-sensitive peripherals. |

FAQ
What microcontroller platforms is STEVAL-FSM01M1 compatible with?
STEVAL-FSM01M1 is natively compatible with STM32 Nucleo boards via ST Morpho extension headers CN7 and CN10. The included firmware STSW-FSM01 targets NUCLEO-F401RE but is adaptable to other STM32 Nucleo platforms through pin mapping and peripheral configuration updates. It does not require Arduino Uno V3 connectors - instead, the Nucleo board mounts atop the STEVAL-FSM01M1.
How does the board support functional safety requirements?
The board implements hardware-level safety features including dual-redundant high-side switch topology (IPS160HF + STL42P6LLF6 per channel), integrated overcurrent/overtemperature diagnostics with dedicated feedback pins, active test-pulse generation for input integrity verification, and galvanic isolation meeting 1 kVRMS requirements - collectively supporting design-in for SIL 2/PL d applications per IEC 62061 and ISO 13849-1.
Can STEVAL-FSM01M1 operate with supply voltages above 24 V?
Yes - the board supports 8–30 V nominal operation and is optionally rated up to 60 V on both input and output sections. This includes CLT03-2Q3 inputs, IPS16xHF outputs, STISO621 isolators, and L7983 regulator, enabling use in 48 V DC industrial systems and brown-out tolerant designs without external voltage conditioning.
What diagnostic capabilities are accessible during runtime?
Runtime diagnostics include per-channel thermal fault signals (via IPS16xHF DIAG pins), SPI-accessible ADC120 measurements of VCC, OUT1, OUT2, and internal rail voltages, configurable cut-off limitation control, and software-triggered test-pulse generation for input channel self-check - all exposed through the isolated digital interface for integration into host firmware monitoring routines.
