The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller and developed by Arduino.cc. The board has 14 digital I/O pins (six capable of PWM output), 6 analog I/O pins, and is programmable with the Arduino IDE (Integrated Development Environment), via a type B USB cable.
Which Atmega is used in Arduino Uno?
ATmega328
The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button.
What is the difference between Arduino Uno and ATmega328P?
In short an ATmega328 is a microcontroller chip found on Arduino Uno boards. ATmega328 microcontrollers are from the 8-bit AVR microcontroller family. There are some Arduino Uno boards that have a surface mount ATmega328 chip. In this case it is a small square chip soldered on top of the Arduino.
What is microcontroller ATmega328?
The ATmega328 is a single-chip microcontroller created by Atmel in the megaAVR family (later Microchip Technology acquired Atmel in 2016). It has a modified Harvard architecture 8-bit RISC processor core.
What are the features of ATmega328?
ATMEGA328P is an 8-bit microcontroller based on AVR RISC architecture….
| ATMEGA328P – Simplified Features | |
|---|---|

| External Oscillator | 0-4MHz @ 1.8V to 5.5V 0-10MHz @ 2.7V to 5.5V 0-20MHz @ 4.5V to 5.5V |
| Internal Oscillator | 8MHz Calibrated Internal Oscillator |
| Program Memory Type | Flash |
What is the difference between Atmega328 and ATmega328P?
There is no major functional difference between them except for power. This microcontrollers are mostly used in Arduino’s. The Atmega 328 function the same like Atmega 328p but the 328p has very low power consumption using the ATMEL’s PicoPower Features. Hence P stands for PicoPower.
How many timers does ATmega328P?
three timer
The Atmega328P has a total of three timer/counters named Timer/counter 0, Timer/counter 1, and Timer/counter 2. The first and last of these are both 8-bit timer/counters and have a maximum value of 255, while Timer/Counter 1 is 16 bits and its maximum is 65,535.
What is Atmega328 used for?
ATmega328 is commonly used in many projects and autonomous systems where a simple, low-powered, low-cost micro-controller is needed. Perhaps the most common implementation of this chip is on the popular Arduino development platform, namely the Arduino Uno and Arduino Nano models.
How do I program an ATmega328 to an Arduino Uno?
Simply use the Arduino Uno as you normally would and program your sketch onto it. Then carefully remove the ATmega328 from your Arduino Uno and use it on the breadboard, wired as we have seen earlier. The ATmega328 holds your sketch in its Flash Memory. So when it is powered up it will start running it, just as if it were in an Arduino Uno.
Who invented the ATmega328 microcontroller?
The ATmega328 was originally developed by Atmel. Atmel was purchased by Microchip Technology in 2016 and now holds the patent to the ATmega328. The original Arduino Uno and its clones used the 28-pin DIP (Dual Inline Package) version of the ATmega328.
The ATmega328. The ATmega328 is a single-chip microcontroller with the following features: 8-bit RISC (Reduced Instruction Set Computer) processor core. Runs at clock speeds from 1MHz to 20MHz. 32Kb Flash Memory. 2Kb SRAM (Static Random Access Memory).
What is Arduino Uno based on?
Arduino Uno is based on ATmega328P Atmel AVR family microcontroller (MCU). This MCU has 32KB of flash, 2KB of SRAM and 1 KB of EEPROM. It has 14 digital IO pins (PORTD – 8pins, PORTC – 6 pins, PORTB – 5pins), 6 Analogue input pins, which can be sampled using on-chip ADC.
