| Development Boards, Kits, Programmers | 1 | Active | The STEVAL-SCR002V1 introduces a simple and innovative AC-DC front-end circuit that allows the designer to perform an inrush current limitation in any converter with input rectifier bridge topologies.
Based on a discrete control circuit made of one Z0110MN SMD triac and two STTH110A diodes, it offers a compact and non-insulated high voltage driver for the mains SCR. The drive circuit synchronizes the SCR gate signals with the AC line polarity and powers directly the SCR gate from the mains. This operation does not generate reverse losses in the SCRs.
This STEVAL-SCR002V1 solid-state solution provides a high reliability, a long service lifetime, an electromagnetic interference reduction, and a faster response compared to electromechanical solutions.
This solution is also compatible with an inrush current limitation performed either in the NTC/PTC bypass mode or in the MCU phase-control mode.
The enable control pin of the SCR driver is referenced to GND_DC. Therefore, an uninsulated power supply or a direct control by the MCU can be used.
With five wires to connect, the STEVAL-SCR002V1 is designed for an easy implementation on existing AC-DC converters for plug-and-play tests.
It is suitable for applications with an RMS current up to 4.3 A (at an ambient temperature of 60°C). |
STEVAL-SILKT01Evaluation kit for industrial PLC solutions targeting SIL3 applications | Evaluation Boards | 1 | Active | The STEVAL-SILKT01 is an evaluation kit designed to implement a PLC solution with hardware architecture designed to meet the requirements coming from functional safety standards IEC61508, EN 62061, EN ISO 13849-1, EN ISO 13849-2, to enable the use as a reference design for factory automation use cases having a hardware platform with safety integrity level SIL3.
The evaluation kit STEVAL-SILKT01 contains one mother board STEVAL-SILKTA01 (main board) and two daughter boards STEVAL-SILKTB01 (actuation board).
The board architecture offers a dual-core data processing based on STM32H743ZG for the STEVAL-SILKTA01 and on STM32G431RB for the STEVAL-SILKTB01.
On the main board (STEVAL-SILKTA01) are available three connectivity interfaces, two of them with differential communication working on RS485 and CAN physical layer, the other one with Ethernet technology to support the Ethernet/IP.
The hardware is coming with the firmware package STSW-SILKT01 based on the STM32Cube architecture and consisting of: application layer, drivers layer with BSP/CMSIS and HAL library, middleware layer. |
| Embedded MCU, DSP Evaluation Boards | 1 | Active | The STEVAL-SILPC01 is a PLC solution with a 1oo2 architecture, featuring the CLT03-2Q3dual channel digital input and the IPS160HF single channel digital output.
The hardware is designed to meet the SIL level. It has been officially assessed by TÜV Italia (TÜV SUD Group) in compliance with SIL 2 / PL d requirements: random failure rates, systematic capability (for the hardware), architectural constraints in accordance with IEC 61508, EN 62061, EN ISO 13849-1, and EN ISO 13849-2 standards.
The system is built around the STM32H723VG microcontroller. It is able to manage connectivity, load actuation and system diagnostic check for power management, digital input/output ICs, and temperature monitoring at the same time.
The solution integrates DC-DC converters in a buck configuration powered by the L7987L and L7983. The switching converters have been designed to provide 3.5 V on the user side and 6 V on the isolated side. With dedicated post regulation circuits, these voltage levels are stepped down to 3.3 V for the MCU, connectivity, and temperature sensor (available on the isolated side) and 5 V for the signal delta isolator (also available on the isolated side).
The CLT03-2Q3 input can detect a fixed DC voltage via a 0-36 V or 4-20 mA sensor, whereas the two IPS160HF allow load driving with a 2.5 A current capability for each output.
Several diagnostic and protection circuits are available on the board to ensure the system proper functionality and meet the IEC61508-2 requirements.
The hardware is supported by STSW-SILPLC firmware package, based on the STM32Cube architecture. It consists of an application layer, a drivers layer with BSP/CMSIS and HAL library, and a middleware layer.
The firmware solution embeds the EtherCAT protocol stack V5.0.8 and X-CUBE-STL-H7 v1.2.0 certified by TÜV Rheinland. The stack library provides dedicated APIs to handle the data packet exchange between the master and the slave. Data consist of a set of commands to drive the load through the on-board IPS on board and manage system diagnostic using dedicated signals. These data types are exchanged using the process data channel of the protocol stack.
A daisy-chain configuration can be implemented to connect more than one sensor node to the same network. In this case, the master generates a common frame with the data to be addressed to all EtherCAT slaves (ECS). Each node identifies its own frame by verifying only the MAC address reported in the frame.
Dedicated documentation related to TÜV assessment on the hardware, such as TN1395 "Analysis of hardware systematic failures and techniques for on-chip redundancy", FMEDA, Assessment on hardware Report TI 722260614 Rev. 0, and the industrialization package, as well as the user manual, are available on demand, by signing a specific NDA. |

The device offers output overvoltage protection (OVP) and over-temperature protection (OTP). It also offers Hiccup-mode protection for when the transformer saturates or the secondary diode fails short, and an output UVP protection that limits the average output current when an output short circuit occurs.
The adapter satisfies energy saving recommendations (EuCoC rev. 5 – Tier 2 and EPS of DOE USA) and EN55022-Class-B Conducted noise emissions.
The small form factor and the output USB connector renders the design suitable for small USB chargers and adapters for mobile phones, tablets and other handheld equipment. |
