Cómo encontrar una hoja de datos para una pieza que no existe en el sitio web del fabricante?

You’ve pretty much got the process down.

Recognize that some parts, such as mask-programmed micro-controllers and perhaps some pre-programmed flash micro-controllers may be house numbered, which means they have a part number assigned by the customer, not the manufacturer, and no information will be forthcoming from the latter, nor will you likely ever find a datasheet. The part may or may not be basically a standard part.

Algunas veces, especially with micro-controllers, you can match

• The package,
• Fabricante (if known)
• The pin pattern (things like power pins, crystal pins, etc.) to reduce the number of options,

sin embargo, it’s not an especially rewarding exercise unless you’re being paid to analyze someone else’s product. The magic is all in the firmware in such cases, and it will be copyright (as well as hardware locked, though that doesn’t slow down some unethical folks much). Try to ask the supplier to help you repair the machine if it is within warranty.
