What are some considerations for designing microcontroller systems in electrically noisy environments?
Application Note AP-125 – Designing Microcontroller Systems for Electrically Noisy Environments describes some considerations for electrical noise and electrically noisy environments. Some of the discussed design considerations are PCB layout, power supply distribution, and decoupling. In addition, shielding and grounding techniques that may help minimize noise susceptibility are reviewed. Special attention is given to automotive and ESD environments.
