The factory defect rate of an MCU (Microcontroller Unit), usually expressed in PPM (Parts Per Million), is a highly variable value that depends on several key factors. For mainstream, mature MCU manufacturers and product lines, the factory defect rate can typically be controlled at a very low level, generally ranging from 10 PPM to 100 … Read more
