• ATmega328 Datasheet

1.What is ATmega328 used for?

• ATmega328 is a popular microcontroller that is commonly used in various projects and autonomous systems where a simple, low-powered, and low-cost micro-controller is needed. It is a single-chip microcontroller based on an 8-bit RISC processor core and is designed by the Atmel corporation. The ATmega328 is used in many different applications because of its affordability and versatility. The most common implementation of this chip is on the popular Arduino development platform, namely the Arduino Uno, Arduino Pro Mini and Arduino Nano models. The Arduino platform provides an open-source platform for creating interactive electronic projects.

2.What are the features of ATmega328?

• ATmega328 is an 8-bit microcontroller that belongs to the AVR family of microcontrollers developed by Atmel (later acquired by Microchip Technology in 2016). It is widely used in various applications, including Arduino boards. Here are some of the features of ATmega328:
  • Architecture: ATmega328 uses the advanced RISC architecture with 131 powerful instructions, most of which can be executed in a single clock cycle. It has a modified Harvard architecture with separate memories for instructions and data.
  • Clock Speed: It can operate at a maximum clock speed of 20 MHz.
    Program Memory: It has a 32 KB ISP flash memory with read-while-write capabilities for in-system programming.
  • Data Memory: It features 2 KB of Static Random Access Memory (SRAM) and 1 KB of EEPROM.
    Pinout: ATmega328 has 28 pins in its package, which can be used as general-purpose input/output (GPIO) lines. It has 23 GPIO pins, including 6 PWM pins.
  • Timers and Counters: It has three flexible timer/counters with compare modes and an on-chip 2-cycle multiplier.
    Analog to Digital Converter: It has a 10-bit ADC with 8 channels.
  • Communication: It features a programmable serial USART for communication.
  • Power Efficiency: It has auto-sleep and an internal temperature sensor that improves power efficiency.
    Supply Voltage: It operates at a recommended supply voltage of up to 5.5V, with an absolute maximum of 6V.

3.How to use Atmega328 in Arduino?

• You can use the ATmega328P chip with a microcontroller board like the Arduino Uno. Simply upload your code to the Arduino Uno as usual, remove the ATmega328P from the board, wire it up and use it on a breadboard. The ATmega328P will hold your sketch in its flash memory. To bootload, the ATmega328P fix the chip on a breadboard, connect the crystal to the 9th and 10th pins of the 328, connect two 22pF capacitors to each of the two legs of the crystal and ground them, and connect pin no: 7 and 20 to a 5V pin of Arduino, and pin no: 8 and 22 to the ground of Arduino. 
• To program the ATmega328P with the Arduino IDE, first, download the ArduinoISP sketch from File > Examples > ArduinoISP, select the Arduino UNO board from Tools > Board, select the port from Tools > Port, and upload the ArduinoISP sketch to your board. After successful uploading, connect the ATmega328P to your Arduino board and select the correct board and port from the Tools menu, and upload your sketch as you would with any other Arduino board.
• Download the breadboard.zip file and extract it. Open the Arduino IDE, go to Tools > Board > Boards Manager and search for MiniCore. Restart your IDE after installing the most recent version. Select the ATmega328 board under Tools > Board, and choose the clock you intend to use.
