New multicore automotive MCU from ST with enhanced security and safety features

Date: 22/04/2015
STMicroelectronics adds new microcontroller (MCU) to its family of multi-core microcontrollers for designing automotive electronics systems.

The new SPC58NE fault-tolerant automotive MCUs are compliant with stringent automotive safety standards such as ISO 26262 ASIL-D and EVITA Medium class, and feature encryption for security, and increased memory size for the storage of vital programs and data for demanding applications used throughout the car. The mission-critical applications include engine management, transmission, anti-lock braking, electric power steering, active suspension, and advanced driver assistance systems (ADAS).

“Security and functional safety compliance are essential to realizing cutting-edge high-reliability System-on-Chip ICs for mission-critical automotive applications,” said Fabio Marchio, Group Vice President, General Manager of ST’s Automotive Microcontroller & Infotainment Division. “Offering a simple and compelling upward-migration path from existing parts, our new automotive MCUs enable improved vehicle performance and economy with no compromises in security, while delivering savings in development by promoting hardware and software reuse.”

Based on the Power Architecture, the SPC58NE product line combines multiple high-performance dual-issue cores with up to 6MB Flash and 768kB internal RAM memory, eight CAN (Controller Area Network) interfaces, and an optimized peripheral set based on the end application. The multiple cores ensure redundancy in these most-important applications to meet the safety and security demands of vehicle manufacturers—and consumers.

The SPC58NE product line is currently available in BGA 292 and LQFP176 package configurations. KGD versions are also planned in the near future. SPC58NE84 is sampling now. ST makes these MCUs using its proprietary in-house 40nm embedded Flash process.
