328p 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.

Which pin number is into pin for ATmega328P?

Pin Number	Description	Function
17	PB3	Digital Pin (PWM)
18	PB4	Digital Pin
19	PB5	Digital Pin
20	AVCC	Positive voltage for ADC (power)

What is the pin count for Atmega328?

Parameter	Value
SRAM	2 KB
EEPROM	1 KB
Package pin count	28 or 32
Capacitive touch sensing channels	16

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 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.

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.

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.

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 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.

How do I program ATMEGA328P with Arduino Uno?

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"

What is the full form of MOSI pin in ATmega328?

MOSI – MOSI stands for Master Out Slave In. This pin is the output pin forMaster and input pin for Slave. Data transfer from Master to Slave takes place through this channel. SCK – This is the SPI clock line (since SPI is a synchronous communication).

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).

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 do I upload codes to ATMEGA328P?

As @Arcatus said, the bootloader allows the chip to be programmed with the RX/TX pins using a USB-serial converter. You can upload your code to the 328P by selecting the programmer you use and holding the shift key down while clicking the upload button.

Is Arduino better than Raspberry Pi?

Arduino is considered a very good board for quick programming and circuit prototyping. On the other hand, Raspberry Pi functions as a learning tool for Computer Programming. However, Raspberry is found useful in many DIY projects as well.

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.

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.

How many timers does the ATmega328 have?

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.
