Freescale Semiconductor and STMicroelectronics, leading semiconductor suppliers to the automotive industry, have introduced a new dual-core microcontroller (MCU) family aimed at in-car safety applications including Adaptive Cruise Control.
Based on the industry-leading 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.
