I am very new to picking microcontrollers for projects. I have a project in which I have 16-bit data coming in from an amplifier/ADC. Simply put, I would like the microcontroller (very low power and in dimensions in range of ~7mmSQ,STM32 based also preferable) to manage the 16-bit data coming in. Is there a specific property in microcontrollers that governs what resolution data it can manage? What is the name of that property? Also, is there a good website for understanding how to choose microcontrollers for projects? Any help appreciated!
I realize the question is very vague but I am just starting out and would love to learn more about how to pick the right hardware any way I can.
