This paper studies software-related microcontroller's conducted electromagnetic interference (SW-cEMI) behaviors when microcontrollers are executing different programs of the same functionality. The SW-cEMI behaviors of different program types, clock sources, and programmable PLL settings are measured and observed. Two major trends of microcontrollers are used as devices under test. The result shows...
This paper proposes a software-related conducted electromagnetic interference (SW-cEMI) model reduction process for two-stage pipelined microcontroller (μC). This paper is based on a black-box transfer function (BBTF) cEMI model building technology and a new proposed decomposition method to reduce the BBTF model (rBBTF) to a reasonable model size. If the number of a μC's machine codes is N and the...
This paper studies the impact of EMC on a programmable PLL feature of both FPGA-based IC and PIC series microcontroller (μC). We use ACTEL FPGA IC the target IC and design the testing board according to IEC standard. By using the TEM-CELL method to measure the electromagnetic radiation from the circuit board, different PLL EMC behaviors of the PIC μC with the FPGA-based design are compared. Generally,...
A FPGA-based microcontroller (μC) is designed. The functional behavior of the FPGA-based μC is same as the microchip PIC 16F84A. The design as well as the power stability (PI) measurement methods is described. The PI is averagely 20dbuV lower than the PIC counterpart.
This paper predicts programspsila effect of time-domain electromagnetic interference (EMI) on a simple microcontroller. Using the instruction current concept and a modified instruction set simulator (ISS) for this purpose, this paper can predict, in the time domain, accurate conducted EMI behaviors when different programs are running on this system. Different program codespsila EMI behaviors are predicted,...
This paper discusses the estimation, measurement, and prediction on the EMI behaviors of a simple PIC controller under different program considerations. Using the "instruction current" concept, this work can predict, in time domain, very accurate current behavior of the conduct emission. This paper also propose a way to modify ICEM model to achieve a good prediction of the impact of EMI...
