MCUs Make Smart Cars More Secure & Connected


ST Microelectronics launched a new series of automotive microcontrollers to develop electronics systems for the next generation of smart cars which are more secure and connected. Using ST’s embedded Flash (eFlash) 40nm process technology, the MCUs are claimed to offer high reliability for automotive applications while enabling car gateways and body modules to be smarter, smaller, and lighter, says the company.

High bandwidth and strong in-vehicle security is offered by the high level of scalability of the SPC58 family. Further, the devices combine Ethernet and ISO CAN FD communication interfaces with the latest Hardware Security Module (HSM) technology to ensure functional integrity of the car’s Electronic Control Units (ECUs), intrusion detection, and protection against malicious attacks.

“Building on the success of our SPC56 Automotive MCU family, which is widely used by Tier-1 and car manufacturers, the new SPC58 enables the automotive industry to raise the bar in security and in-car communications,” said Fabio Marchio, General Manager Automotive Digital Division, STMicroelectronics. “The next generation of smarter cars will rely on electronic systems based on MCUs that provide the best combination of performance, low power consumption, high security, and robustness. ST’s SPC58 MCU lines meet all these needs, making them the leading solutions for next-generation in-car controllers.”


Key benefits of the SPC58 family include ASIL-B (Automotive Safety Integrity Level) compliance, the highest number of ISO CAN-FD and Ethernet communication channels on the market, assured security via the built-in HSM and related security firmware that ensure the highest protection against malicious attacks, option to support “Over the Air” (OTA) requirements allowing smart and wireless SW update.

New ThunderX Processors For Accelerated Performance

Allowing reuse of existing software, development tools, and hardware, the MCUs offer easy portability of applications from SPC56 to SPC58. Further, the MCUs claim to double the performance of previous-generation solutions, with multi-core architecture, higher system frequency, and faster memory-access time.

“Tomorrow’s connected car will communicate with everything, from its internal systems such as transmission, advanced driver-assistance electronics, and front panel to roadside infrastructure, emergency services, and other cars. And it will have to provide the highest level of security,” added Marchio. “The SPC58 Automotive MCUs, with their unique combination of performance, connectivity, security, and scalability, allow car makers and their sub-system suppliers to set new standards in ensuring a safer, greener, and more enjoyable driving experience.”

Samples of the SPC58 B-, C- and G-Line MCUs have been provided to lead customers and full production is scheduled for Q1 2017.
