Product details

Overview

STEVAL-SILKT01 from STMicroelectronics is an industrial safety evaluation kit implementing a dual-core PLC architecture for SIL3/PLe-certified factory automation systems, featuring STM32H743ZG (480 MHz, 1 MB Flash/1 MB RAM) and STM32G431RB (170 MHz, 128 KB Flash) MCUs, galvanic isolation via five STISO621WTR devices, dual digital I/O redundancy (IPS1025H high-side + IPS4260L low-side outputs, CLT03-1SC3 inputs), and real-time Ethernet/IP, CAN FD, and RS-485 interfaces.

For engineers reviewing the STEVAL-SILKT01 datasheet, STEVAL-SILKT01 pinout, STEVAL-SILKT01 application, or STEVAL-SILKT01 equivalent, this kit serves as a reference design for functional safety validation in programmable logic controller development, hardware-level redundancy verification, diagnostic coverage assessment (>90%), and industrial communication protocol integration under IEC61508-2, EN 62061, and ISO 13849-1/2 compliance requirements.

Technical Context

The kit implements hardware-level redundancy across processing (dual-core STM32H743ZG + STM32G431RB), digital I/O (dual-channel CLT03-1SC3 inputs with independent detection paths; IPS1025H + IPS4260L outputs with separate drive logic and feedback), and isolation (five STISO621WTR 2-channel isolators managing serial comms, I/O signal transfer, and diagnostic signaling). All safety-critical paths include dedicated power domains and independent supervision.

Real-time deterministic communication is enabled through three concurrent interfaces: Ethernet/IP via DP83848MPHPEP PHY with MII interface, CAN FD via MAX3051ESA+ transceiver with FDCAN peripheral routing, and RS-485 via ST3485EI transceiver with half-duplex DE/RE control - all electrically isolated and synchronized to the dual-core safety firmware stack STSW-SILKT01.

Key Specifications

Parameter	Value and Actual Design Meaning
Safety Certification	Validated to IEC61508-2 SIL3, EN 62061 SIL3, EN ISO 13849-1/2 PLe - enables use as reference hardware for certified PLC designs.
Processing Architecture	Dual-core: STM32H743ZG (480 MHz Cortex-M7, 1 MB Flash/1 MB RAM) for safety runtime + STM32G431RB (170 MHz Cortex-M4, 128 KB Flash) for actuation control.
Digital I/O Redundancy	Two independent digital input channels (CLT03-1SC3) and dual-output architecture (IPS1025H high-side + IPS4260L low-side) with separate feedback paths and overload/overtemperature diagnostics.
Galvanic Isolation	Five STISO621WTR 2-channel isolators (10 total channels) providing reinforced isolation (5 kVRMS) for MCU interconnect, digital I/O, diagnostics, and communication signals.
Communication Interfaces	Ethernet/IP (MII, DP83848MPHPEP), CAN FD (FDCAN + MAX3051ESA+), RS-485 (ST3485EI) - all differential, isolated, and supported by STSW-SILKT01 middleware stack.
Diagnostic Coverage	Hardware- and firmware-implemented diagnostics achieving >90% DC per IEC61508 Annex H, including memory BIST, clock monitoring, watchdog supervision, and I/O path validation.

FAQ

What firmware is included with STEVAL-SILKT01?

The kit ships with STSW-SILKT01 firmware based on STM32Cube architecture, comprising safety application layer, BSP/CMSIS/HAL drivers, and middleware supporting Ethernet/IP, CAN FD, and RS-485 protocols. It includes diagnostic routines for memory, clocks, I/O, and thermal monitoring, all structured to meet SIL3 software development requirements per IEC61508 Part 3.

Does STEVAL-SILKT01 support third-party safety certification services?

Yes - the board's hardware architecture, schematic documentation (DB5133), and firmware source code are provided to enable engagement with notified bodies (e.g., TÜV Rheinland, SGS) for SIL3 certification. ST supplies safety manuals, FMEDA reports, and diagnostic coverage analysis aligned with IEC61508 Annex H and ISO 13849-2 Annex K.

Can the daughter boards be used independently of the main board?

No - STEVAL-SILKTB01 actuation boards require the STEVAL-SILKTA01 main board for power distribution, isolation control, and dual-core coordination. The boards communicate exclusively via isolated SPI and share synchronized safety state machines; standalone operation is not supported per the safety architecture design.

What external power supply is required?

The kit accepts 24 V DC nominal input (18–36 V range) via VIN_Conn terminal block. Onboard L7987L DC-DC converters generate isolated 3.5 V and 3.3 V rails for MCU, I/O, and communication subsystems, with undervoltage lockout and thermal shutdown protection integrated at silicon level.
