Abstract

This paper presents a predictive SPICE model for the radiated ElectroMagnetic Interferences (EMI) of a 32-bit microcontroller. The aim of this work is to be able to predict, during the design stage, the level of electromagnetic emissions in order to establish pinout, design or layout rules. This model is intended to represent the EMI behavior of a microcontroller when it is running in a noisy mode (reading accesses to the eNVM Flash memory and CPU running). The simulated results have then been correlated with radiated emission measurements. The model has been simulated with the Eldo simulator while the measurements have been done on a 32-bit STMicroelectronics^© microcontroller, following the IEC 61967-2 standard.
