Why Microcontrollers Don’t Integrate All Peripheral Circuits: A Deep Dive into the Technical Logic Behind It
When designing a microcontroller system, the first step is often to build a “minimum system”: the chip itself, power supply, crystal oscillator, reset circuit, and a few filter capacitors. Many beginners may wonder: since these peripheral circuits are so standard and necessary, why don’t chip manufacturers directly integrate them into the microcontroller? Wouldn’t that be … Read more
