Key Features:

1. Basic Processing Power: Suitable for simpler tasks like controlling lights, sensors, and motors.
2. Memory Limitations: 8-bit MCUs have smaller memory addressing capabilities, making them ideal for applications with lower data storage needs.
3. Low Power Consumption: These MCUs are energy-efficient, making them suitable for battery-powered applications.
4. Cost-Effective: 8-bit MCUs are cheaper, making them perfect for mass-produced, low-cost devices.
5. Example: The AVR ATmega328, found in the Arduino UNO, is a popular 8-bit MCU, widely used for hobby projects and educational purposes.

Applications of 8-bit MCUs:

• Home Appliances: Microwaves and toasters.
• Toys and Gadgets: Simple toys with embedded control systems.
• Robots: Low-cost robots with basic functions.
• Embedded Systems: Basic sensors and alarms.

Peripheral ICs

Peripheral ICs enhance MCU functionality by providing specialized features, such as data conversion, communication, and power management.

Types of Peripheral ICs:

1. ADC/DAC: Convert analog signals to digital and vice versa for signal processing.
2. Power Management ICs: Handle voltage regulation, battery charging, and power distribution.
3. Communication Interfaces: External ICs for USB, Bluetooth, Wi-Fi, and Ethernet capabilities.
4. Memory ICs: External memory chips like EEPROM and Flash to extend storage for larger systems.
