Power-architecture automotive MCU series targets connected applications

May 13, 2016 // By Graham Prophet
STMicroelectronics’ latest MCU series develops its automotive-focussed product line with features for more secure and connected cars. Presented as power-efficient and real-time-capable, the MCUs bring Power Architecture-based devices in 40nm flash technology to car body and security applications.

The series comprises three three product lines; SPC58 B-Line, SPC58 C-Line, and SPC58 G-Line, which offer from 512 kB to 6 MB of embedded Flash memory. The high level of scalability allows the SPC58 family to address the need for in-car automotive networks with high bandwidth and strong in-vehicle security. The devices combine Ethernet and ISO CAN FD communication interfaces with Hardware Security Module (HSM) technology to ensure functional integrity of the car’s Electronic Control Units (ECUs), intrusion detection, and protection against malicious attacks.


ST’s in-house embedded Flash (eFlash) 40 nm process technology integrates high performance and automotive-grade reliability in very small packages, enabling car gateways and body modules to be smarter, smaller, and lighter.


“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 SPC58 family for car body and security applications, offers a scalable line with;

ASIL-B (Automotive Safety Integrity Level) compliance;

The highest number of ISO CAN-FD and Ethernet communication channels available;

Double the performance of previous-generation solutions, thanks to the multi-core architecture, higher system frequency, and faster memory-access time;

40nm Flash technology enables high integration and performance in very small packages – as few as 32 pins;

Companion MCU for camera or telematics applications;

Suited for in-car stand-alone and integrated gateways;

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;

Easy portability of applications from SPC56 to SPC58, with high reuse of existing software, development tools, and hardware experience.
