Freescale Semiconductor and STMicroelectronics have introduced a new dual-core microcontroller (MCU) family aimed at functional safety applications for car electronics. The 32-bit devices help engineers address the challenge of applying sophisticated safety concepts to comply with current and future safety standards. The dual-core MCU family also includes features that help engineers focus on application design and simplify the challenges of safety concept development and certification.
Based on the 32-bit Power Architecture technology, the dual-core MCU family, part-numbered SPC56EL at ST and MPC564xL at Freescale, is ideal for a wide range of automotive safety applications including electric power steering for improved vehicle efficiency, active suspension for improved dynamics and ride performance, anti-lock braking systems and radar for adaptive cruise control.
The dual-core MCU family resulted from the two companies’ joint development program. The devices are designed specifically to address the requirements of the International Electrotechnical Commission (IEC) 61508 and International Organization for Standardization (ISO) 26262 safety standards that are being applied to the growing number of safety-critical systems in road vehicles.
The single-chip MCUs combine two high-performance cores with up to one megabyte of flash memory and an optimized peripheral set for safety and motor-control applications (supporting control of up to two brushless 3-phase motors). The dual-core architecture reduces the need for duplication of components at a system level, and therefore lowers overall system costs.
The dual-core architecture also provides unique flexibility by allowing the user to select lockstep or dual parallel processing (independent core operation) modes, enabling support of multiple safety architectures that the user can configure to achieve the required balance between safety and performance level.
Initiated in February 2006, the ST – Freescale joint development program has been accelerating innovation in the automotive industry by developing microcontroller products that provide high levels of power and enhanced intelligence in many segments of car electronics.
