2021 年 3 月 02 日

AN89056 describes the PSoC® 4 IEC 60730 Class B and IEC 61508 safety integrity level (SIL) Safety Software Library and includes example projects with self-check routines to help ensure reliable and safe operation. You can integrate the library routines and examples included in the example projects with your application. This application note also describes the API functions that are available in the library.


Today, the majority of automatic electronic controls for home appliance and industrial products use single-chip microcontroller units (MCUs). Manufacturers develop realtime embedded firmware that executes in the MCU and provides the hidden intelligence to control home appliances and industrial machines. MCU damage due to overheating, static discharge, overvoltage, or other factors can cause the end product to enter an unknown or unsafe state.
