The ATmega328P is a popular 8-bit microcontroller from the Atmel (now a part of Microchip Technology) AVR family. It is widely used in a variety of embedded systems and DIY projects due to its versatility, performance, and ease of use. Here are some key features and specifications of the ATmega328P microcontroller:
Architecture: The ATmega328P uses the Harvard architecture and is based on the Modified Harvard Architecture, which combines the features of both Harvard and von Neumann architectures. It features a single-cycle execution, making it efficient for various applications.
CPU Speed: The ATmega328P typically operates at a clock speed of 16 MHz, but it can run at lower frequencies for power-saving applications.
Flash Memory: The microcontroller has 32KB of in-system programmable Flash memory for storing the program code.
SRAM: It has 2KB of static RAM (SRAM) for data storage during program execution.
EEPROM: The ATmega328P has 1KB of electrically erasable programmable read-only memory (EEPROM) for non-volatile data storage.
I/O Pins: It offers 23 general-purpose I/O pins, which can be used for various digital and analog inputs and outputs.
Analog-to-Digital Converter (ADC): The ATmega328P includes a 10-bit ADC with multiple channels, making it suitable for analog sensor interfacing.
Timers and Counters: It features three 16-bit timers/counters, including a 16-bit real-time counter (RTC).
Communication Interfaces: The ATmega328P supports UART (serial communication), SPI (Serial Peripheral Interface), and I2C (Inter-Integrated Circuit) communication protocols.
Voltage Supply: The microcontroller typically operates at 5V, but it has a wide voltage supply range, from 1.8V to 5.5V.
Power-Saving Modes: It provides several power-saving modes to reduce power consumption when the microcontroller is not actively processing.
Operating Temperature Range: The ATmega328P is designed to operate within a wide temperature range, making it suitable for various environments.
Bootloader Support: Many ATmega328P-based development boards and products include a bootloader, allowing for easy programming via a serial connection.
