CAST Adds New SafeSPI #Controller to its Functional Safety IP Core Product Line Woodcliff Lake, New Jersey — November 19, 2024—Semiconductor intellectual property provider CAST, in collaboration with Silesia Devices, today announced a new IP core that implements the Serial Peripheral Interface for Automotive Safety (SafeSPI), an emerging open standard that adds Functional Safety and interoperability features to the de-facto Serial Peripheral Interface (SPI) industry standard.   Why SafeSPI?   Conventional SPI is a four-wire interface for synchronous communication that has been extremely popular, especially for linking sensors with processors in automotive systems. However, there has been no formal industry standard for SPI, and integrating multiple devices into a complex system gets complicated when different developers employ custom SPI variations. Moreover, conventional SPI does not provide for Functional Safety design practices, which is of paramount importance for automotive systems. Artemis Couroupaki
