Application of FRAM in Vehicle Control Unit VCU

The VCU hardware consists of standardized core module circuits (32-bit main processor, power supply, memory, controller area network) and VCU-specific circuits (sensor acquisition, etc.). ); The standardized core module circuit can be transplanted into MCU and building management system, and the platform hardware has good portability and expansibility. With the development of automotive processor technology, VCU has gradually transitioned from a 16-bit processor chip to a 32-bit processor chip, and the 32-bit processor chip has become a mainstream product in the industry.

VCU hardware composition

Application of FRAM in Vehicle Control Unit VCU

The VCU is the core Electronic control unit that implements vehicle control decisions. Generally speaking, only new energy vehicles are equipped with such devices, and conventional fuel vehicles do not have such devices. The VCU judges the driver’s driving intention by collecting signals such as accelerator pedal, gear position, and brake pedal. By monitoring the speed and temperature of the vehicle and other information, the VCU can judge and process it, and then send the vehicle operating status control command to the power battery system, and control the operating mode of the on-board accessory power system. The VCU has fault diagnosis and protection and storage functions for the entire vehicle system.

Application of FRAM in Vehicle Control Unit VCU

FRAM is a non-volatile memory chip memory that can perform high-speed random access and has the characteristics of high write endurance, so it can meet the needs of such applications with the best performance. Fujitsu acts as the agent of Insun Microelectronics to provide technical and application solution product services.
