Now, letβs discuss the features! Microcontrollers include on-chip RAM and ROM. Who can explain why these are important?
RAM is for temporary data, and ROM is for storing the program, right?
Exactly! RAM stores data while the program is running, and ROM retains the program after power off. They also contain timers and ADCs. What do you think is the role of ADCs?
They convert analog signals to digital, so the processor can understand them!
Correct! Understanding these features helps us appreciate how microcontrollers are designed to interact with the real world.

On-chip RAM and ROM
Timers, ADCs, communication interfaces
Detailed Explanation
Microcontrollers come with built-in features such as RAM (for temporary data storage) and ROM (for permanent data storage). They also include timers that help in managing time-sensitive tasks, ADCs (Analog-to-Digital Converters) that convert analog signals to digital data, and various communication interfaces that allow them to connect and interact with other devices.
Examples & Analogies
Imagine a smart thermostat in your home. Inside, a microcontroller manages all its functionalities: it uses RAM to temporarily hold the current temperature, ROM to store the heat settings, a timer to know when to heat or cool the house, and communication interfaces to send data to your smartphone.
