Atmega328

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, Arduino Pro Mini and Arduino Nano models.

Why ATmega328 is used in Arduino Uno?

The ATmega328 on the Arduino Uno comes preprogrammed with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the original STK500 protocol (reference, C header files).

What does 328 mean in ATmega328?

328 in Atmega 328 means.. 32kB of ISP flash and 8 bit controller in the microcontroller chip , i.e the input output processing is done on 8 bits.

Is Arduino and ATmega328 same?

It differs from the ATmega328 in that it is only available in a surface mount package, so can't be inserted into and removed from a socket on the Arduino. It also has more memory, more pins and more built-in hardware peripherals than the ATmega328.

Why it is called ATmega328P?

And the name of this Micro Controller is ATmega328p which is a product of ATmel. 32 - represents it's flash memory capacity that is 32KB. 8 - represents it's cpu type that is of 8 bit. p - simply denotes that it needs less power to work than it earlier version.

What is difference between ATmega328 and ATmega328P?

DIFFERENCE BETWEEN ATMEGA328/328P Atmega328P just consumes lower power than Atmega328. Look up the numbers in the datasheet. This means that the 328P is manufactured in a finer process than the 328. Ex: 328 could be a 90nm process and 328P could be a 60nm process.

Which microcontroller is used in Arduino?

Arduino UNO is a microcontroller board based on the ATmega328P. 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.

Why Arduino Uno is best?

Arduino UNO is a low-cost, flexible, and easy-to-use programmable open-source microcontroller board that can be integrated into a variety of electronic projects. This board can be interfaced with other Arduino boards, Arduino shields, Raspberry Pi boards and can control relays, LEDs, servos, and motors as an output.

What kind of code is Arduino?

Arduino code is written in C++ with an addition of special methods and functions, which we'll mention later on. C++ is a human-readable programming language.

How do you program ATmega328?

Programming the ATmega328P Select the correct board in the Arduino IDE by going to Tools > Board and selecting "ATmega328 on a breadboard (8 MHz internal clock)" Select the correct programmer in the Arduino IDE by going to Tools > Programmer and selecting "Arduino as ISP"

How do I program ATmega328P without Arduino?

You can either program the ATmega using the Arduino board, but for this you will need to upload the Arduino bootloader on the ATmega or you can purchase a bootloaded ATmega328, or you can use ATmel studio, but with this you will need an external programmer and a software like Xtreme burner to burn that code.

Is Arduino a microcontroller?

Arduino (/ɑːrˈdwiːnoʊ/) is an open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.

What is the operating voltage of ATmega328?

Explanation: The operating voltage of the Atmega328 is 1.8V to 5.5V. Provide any voltage lower than that and the chip will not function.

What is the difference between Arduino Uno and ATmega328?

In the UNO SMD (Surface Mounted Device) the microprocessor chip (ATmega328) is integrated and soldered onto the board; while in the standard UNO, the ATmega328 is DIP (Dual In-line Packaged), which means that the microprocessor chip can easily be removed and replace if necessary.

How much flash memory does the ATmega328 have?

An ATmega328 has 32 KByte of flash memory, enough to store fairly substantial sketches.

Which Arduino board use the 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 crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.

How many pins ATmega328P has?

Atmega328 has 28 pins in total. It has 3 Ports in total which are named as Port B, Port C and Port D.

What is Arduino compiler?

The Arduino IDE is an open-source software, which is used to write and upload code to the Arduino boards. The IDE application is suitable for different operating systems such as Windows, Mac OS X, and Linux. It supports the programming languages C and C++.
