NTSafeFlex STM32

MicroController based evaluation board with additional Software Library for functional safety solutions up to SIL 3 and PLe, Cat4

Advantages of the STM32 SafeFlex from NewTec

The NTSafeFlex STM32 consists of an dual STM32-based evaluation board. With two small MicroControllers together with a Safety Software Library in safety related systems. A considerable reduction in costs for development and certification is achieved and the time to market is reduced noticeably.

The concept of the NTSafeFlex STM32 has already been utilized in several safety projects. It assists you to reduce risks, design costs, design time, process overhead. It improves your platform development, flexibility, modularity and safety integrity level (SIL).

Typical fields of application are e.g. safety control logic, motor supervision and general safety applications with low performance standards.

The NTSafeFlex STM32 development board implements proven architecture and design principles to fulfill all the requirements of the following safety standards:

  • IEC 61508 standard up to SIL 3
  • ISO 13849 standard up to Pl e Cat. 4

STM32 NTSafeFlex: Customer benefits

STM32 NTSafeFlex: Typical applications

  • Industrial
  • Robotic
  • Medical
  • Energy Management
  • etc.


Key Features

1oo2 architecture
HFT = 1 (IEC 61508)
Two STM32G070
SIL3 ready
24V Input

  • Compatible with all STM32G0xx controllers in 48 Pin LQFP package
  • Power-Monitoring
  • Arduino & STM Nucleo compatible connector
  • 17 IOs available for customer use (I2C/SPI/GPIOs)
  • Debug UART on UART -> USB converter (also available for customer application use)


With the Nucleo/Arduino compatible connector, this solution can be directly used in many user setups implemented on an extension board. Sample extension boards are available. So you can use the NTSafeFlex STM32 for your own safety development to design and realize systems, for instance:

  • Safe system shutdown
  • Safe motor supervision
  • etc.
