Overview

The ReSCuV2 is a safety-related chip solution that has been specially designed and developed in accordance with the criteria of IEC 61508 for use in safety-critical applications. The system architecture is designed as an asynchronous multiprocessor system. The architectural design of the ReSCuV2 not only allows it to be used in the field of process technology (IEC 61508 / IEC 61511), but its special safety architecture also offers major advantages for use in safety applications in mechanical engineering (EN ISO 13849), automotive technology (ISO 26262) and railroad technology (CENELEC 5012x). A configurable digital input/output concept offers high flexibility. This concept allows the connection of an application to be realized flexibly and easily and offers great advantages in application adaptation compared to conventional structures. Furthermore, the ReSCuV2 offers analog input/output interfaces with a width of 16 bits, which predestine it for a wide field of signal and control technology in the IoT. Different interfaces are available for communication with the outside world, offering a wide range of communication options. This makes the ReSCuV2 the ideal safety core in embedded and safe IoT applications.
