Atmega328p pinout

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

What are the ports in case of Atmega328P?

Three ports, Port B, Port C, and Port D can be used as general I/O pins. Port B and Port D are used as Digital I/O while Port C is used for Analog I/O.

How do you define pins in Atmega328P?

The Atmega328 has 28 pins. It has 14 digital I/O pins, of which 6 can be used as PWM outputs and 6 analog input pins. These I/O pins account for 20 of the pins.

What is AVCC pin in Atmega328P?

AVCC is power for the analog circuitry (Port C pins and internal A/D) in the Atmega. L1 is an inductor intended to make cleaner analog power. That is the old serial Arduino too. Newer ones have USB interface instead, with AVCC connected to VCC.

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.

Why ATmega328 is used in Arduino?

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.

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.

How do I know if ATMEGA328P is working?

Just install the bootloader of Arduino into the ATMEGA328 & then you can easily swap the ATMEGA into the arduino. Now just write a program cide & check if it is working or not. You can get many examples in the Arduino software also. The most simple code is blinking.

What is the reset pin in ATmega328P?

The RESET pin on the ATmega328 needs to be connected to VCC. You can either wire the RESET pin directly to 5V or you can 'tie it high' by connecting the RESET pin to VCC through a resistor. This will allow you to add a momentary reset button.

What are IO pins?

An input/output pin, or I/O pin, is the interface between a microcontroller and another circuit. It can be configured in the microcontroller's software to be either an input or an output. On the Arduino, this configuration is accomplished using the pinMode() function.

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 VCC and AVCC?

VCC pin is used to power all the digital components of the microcontroller whereas AVCC is used to power all analog components (Port C pins and internal A/D).

What is VCC and Vin?

VCC is only for the chip and requires 5V. Vin (nominally 7-12V) and 5V (must be 5V in, or can be 5V out) are extra elements on various Arduino boards.

How do I connect to ATmega328P?

Open Mfile and follow these steps:

Click MakeFile -> Enable Editing of Makefile.
Click MakeFile -> Main file name. ...
Since we are using a 16MHZ Quartz Crystal Clock we need to specify the processor frequency. ...
Click MakeFile -> MCU type -> ATMega -> atmega328p. ...
Click MakeFile -> Port -> USB.

Is ATMEGA328P a microcontroller?

The ATMEGA328P-PN is a popular microcontroller due to it being a major component in the Arduino board products. The ATMEGA328P-PN is the 8-bit RISC heart of the Arduino Uno and Nano, with a maximum clock frequency of 20MHz, 32KB program FLASH, and 2KB of RAM.

Is Arduino and ATmega same?

Difference Between Arduino and ATmega2560 AVR 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.

What is the difference between Arduino Uno and ATMEGA328P?

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.
