基于ARM和FPGA设计的电机控制SiP电路OA

Traditional motor control circuits generally adopt discrete components.These discrete circuits are laid out on PCBs according to predefined connection rules,yet they suffer from bulky volume and low reliability,failing to satisfy the miniaturization and lightweight development needs of motor control systems.System-in-package(SiP)can use advanced processes to assemble and integrate multiple IC chips and various types of components on a single packaging substrate,forming an electronic information system with specific functionalities.A SiP circuit of motor control is designed based on SiP technology.The SiP circuit includes an advanced RISC machine(ARM)bare die and a field programmable gate array(FPGA)bare die,which are connected by Wire-bond technology and stacked in a PBGA321 substrate to form the SiP circuit.In comparison with motor control system designed with separate ARM and FPGA architectures,the SiP volume is reduced by more than 50%and the quality is reduced by more than 60%,which effectively solves the large-size problem existing in traditional PCB board-level motor control circuits,and achieving the goals of miniaturization and high reliability.The testing results show that this circuit can meet the design requirements and has a certain application prospect in the field of motor control.
