The devices, said to offer a hardware based solution to ISO26262 ASIL-D compliant and high performance real time system requirements for mid and high end powertrain applications, combine compliance with stringent automotive safety standards, encryption for security and increased memory. According to the company, the parts are suited to mission critical applications such as engine management, transmission, anti-lock braking, electric power steering, active suspension and advanced driver assistance systems.
Fabio Marchio, general manager of ST's automotive microcontroller and infotainment division, said: "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."
The single chip 32bit devices are part of ST's Power Architecture range. Called the SPC58NE product line, the parts feature multiple high performance dual issue cores with up to 6Mbyte of flash and 768kbyte of RAM. The devices feature three e200x4d Power Architecture compliant dual issue cores, with two paired in lockstep. Also included is a lightweight signal processing auxiliary processing unit to handle DSP related tasks.
There are also eight CAN interfaces and a peripheral set that can be optimised for the end application. The multiple cores are said to ensure redundancy to meet safety and security demands.
The SPC58NE product line is currently available in BGA 292 and LQFP176 packages.
