Stop guessing chip part numbers. This video breaks down the standard naming conventions used by major manufacturers. Using real examples from STMicroelectronics (STM32F042K4T6) and Analog Devices (AD644ASH/883B), you'll learn exactly what each letter and number means – brand, series, pins, Flash size, package, temperature range, and screening level. Plus, how to decode marking codes on tiny chips for procurement. No fluff – just the rules you need to order the right parts every time.
