Infineon introduces next-generation Automotive Security Controller SLI37

With increasing electrification and connectivity, vehicles are at greater risk of cyberattacks, which can have serious consequences. For this reason, it is crucial that automotive manufacturers provide adequate protection of telematics data. Infineon Technologies therefore introduces the SLI37 automotive security controller: an easy to design in and reliable trust anchor to secure safety-critical automotive applications like 5G-ready eUICC (eCall), V2X communication, car access or SOTA updates.

The unique and robust chip design of the SLI37 offers an extended temperature range as well as a lifetime of 17 years. While it comes with benchmark quality resulting in very low failure rates, its biggest advantage is the ability to be used for multiple applications. For this reason, OEMs can focus on a single qualification and design-in process.

With more than 100 million eSIMs in the field, Infineon’s SLI series has already proven its reliability. Now it additionally offers all automotive qualifications and certifications required by the industry including CC EAL 6+ and AEC-Q100. Together with Infineon’s long-term supply commitment and quality support, it enables the automotive industry to build the next generation of connected cars without taking security risks.
