Automotive MCU Enables Secure Remote Updates

STMicroelectronics latest high-performance, multi-core multi-interface automotive microcontroller (MCU) boasts state-of-the-art security and generous on-chip code storage. The Chorus automotive MCU is said to be among the industry’s first gateway/domain-controller chips capable of handling major OTA updates securely.

 

With three high-performance processor cores, more than 1.2 MB of RAM and on-chip peripherals, the SPC58 H Line joins the Chorus Series of automotive MCUs and can run multiple applications concurrently to allow more flexible and cost-effective vehicle-electronics architectures. Two independent Ethernet ports provide high-speed connectivity between multiple Chorus chips throughout the vehicle and enable responsive in-vehicle diagnostics. Also featuring 16 CAN-FD and 24 LINFlex interfaces, Chorus can act as a gateway for multiple ECUs (electronic control units) and support smart-gateway functionality via 2 Ethernet interfaces also on-chip.

SENSORS EXPO & CONFERENCE

Sensors 2019 Hits Silicon Valley June 25-27!

Join 7,000+ engineers this June in San Jose at the sensor industry’s biggest event! With 65+ Technical Sessions, 100+ Leading Speakers, 10 new and updated tracks, and 300+ Interactive Exhibits, there’s more opportunity than ever to connect with this booming industry and the technologies driving it. See thousands of the newest technologies in action, learn about the latest applications, and develop invaluable partnerships at the only event dedicated to sensors, connectivity, and systems.

 

To protect connected-car functionalities and allow OTA updates to be applied safely, the chip contains a Hardware Security Module (HSM) capable of asymmetric cryptography. Being EVITA Full compliant, it implements industry-leading attack prevention, detection, and containment techniques. 

 

SPC58 Chorus H line is software friendly and offers the SPC5 Studio development Environment as well as production ready AUTOSAR MCAL drivers, Security Firmware and Safety Libraries.

 

The SPC58NH92x can be ordered in various configurations, at prices starting from $17. Samples are available now to lead customers, with production expected to begin in middle of 2020. Further information can be extracted from the product page and also from the datasheet.
