This application note explains ST Microcontroller EMC features and compliance standards to help application designers reach the optimum level of EMC performance.
The document addresses the increasing demand for high-performance microcontrollers, which inherently increases noise emission and sensitivity. It aims to explain how to apply EMC hardening techniques in firmware, PCB layout, and system design.
The guide covers EMC definitions, characterization of ST Microcontrollers regarding susceptibility (EMS) and interference (EMI), specific design strategies including I/O features and power management, and practical guidelines for hardware, handling, and firmware.
