Freescale Semiconductor and STMicroelectronics announced the ST SPC56EL and Freescale MPC564xL dual-core microcontroller (MCU) family for car electronics. The 32-bit devices enable engineers to 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.
The ST SPC56EL and Freescale MPC564xL dual-core MCU family are based on the 32-bit Power Architecture technology. The devices are ideal for 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.
