Embedded-flash MCUs features target automotive safety, security

April 22, 2015 // By Graham Prophet
These embedded-flash microcontrollers from STMicroelectronics are multi-core devices that support functional safety and encryption in automotive systems

Added to ST’s multi-core microcontroller (MCU) family, these devices are aimed at making cars safer. They are the first to be launched with ST’s proprietary in-house 40nm embedded Flash process.

The new automotive MCUs combine compliance with the most stringent automotive safety standards, encryption for security, and increased memory size for the storage of vital programs and data, strengthening ST’s product line of fault-tolerant microcontrollers for demanding applications throughout the car. These 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 realising 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.”

Part of ST’s Power Architecture single-chip 32-bit automotive-MCU family, the SPC58NE product line combines multiple high-performance dual-issue cores with up to 6 MB Flash and 768 kB internal RAM memory, eight CAN (Controller Area Network) interfaces, and an optimised 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.

The SPC58NE product line is currently available in BGA 292 and LQFP176 package configurations. KGD (known-good dice) versions are also planned in the near future. Compliant with the ISO 26262 ASIL-D and EVITA Medium class, the SPC58NE84 is sampling now.
