Used in ARDUINO UNO, ARDUINO NANO and ARDUINO MICRO boards.There are hundreds of applications for ATMEGA328P: Below is the pin mapping between Arduino Uno and ATmega328P chip. Once Arduino program is burnt into the IC, it can be removed and used in place of Arduino board, along with a Crystal oscillator and other components as required for the project. This IC with bootloader can be placed on Arduino Uno board and burn the program into it.

#ARDUINO UNO PINOUT DATASHEET INSTALL#

For that first you need to install the Arduino bootloader into the chip (Or you can also buy a chip with bootloader – ATMega328P-PU). Since ATmega328P is used in Arduino Uno and Arduino nano boards, you can directly replace the arduino board with ATmega328 chip. Disconnect the programmer, connect the appropriate peripherals for the controller and get the system started.Burn the HEX file of written program in ATMEGA328P flash memory using this program.

#ARDUINO UNO PINOUT DATASHEET SOFTWARE#

Run the programmer software and choose the appropriate hex file.

You can also program ATMEGA328P using ARDUINO UNO board.

Choose the programming device (usually SPI programmer made for AVR controllers) which establishes communication between PC and ATMEGA328P.

#ARDUINO UNO PINOUT DATASHEET CODE#

This HEX file contains the machine code which should be written in controller flash memory.

Make the IDE generate HEX file for the written program after compiling.

After writing the program, compile it to eliminate errors.

ATMEGA328P programming can also be done in ARDUINO IDE.

IDE program for AVR controllers is ‘ATMEL STUDIO’.

#ARDUINO UNO PINOUT DATASHEET FOR FREE#

You can download the IDE program for free in company websites.

Write the functions in programming language in IDE programs.

List the functions to be executed by controller.

After dumping this program code, the controller executes this code and provides appropriate response.Įntire process of using an ATMEGA328P goes like this: Without programming controller simply stays put without doing anything.Īs said, first we need to program the controller and that is done by writing the appropriate program file in the ATMEGA328P FLASH memory. Controller simply executes the program provided by us at any instant. These all features add together promoting ATMEGA328P further.ĪTMEGA328 is used similar to any other controller.

Also with in chip temperature sensor the controller can be used at extreme temperatures.

With advanced RISC architecture, the controller executes programs quickly.

With Watchdog timer to reset under error it can be used on systems with minimal human interference.

With various POWER SAVING modes it can work on MOBILE EMBEDDED SYSTEMS.

With program memory of 32 Kbytes ATMEGA328P applications are many.

ARDUINO boards are also developed on this controller because of its features. Note: Complete technical details can be found in the ATMEGA328P Datasheet linked at the bottom of this page.Īlthough we have many controllers ATMEGA328P is most popular of all because of its features and cost. 40☌ to +105☌(+105 being absolute maximum, -40 being absolute minimum) Programmable Watchdog Timer with Separate On-chipOscillator Two 8-bit counters with Separate Prescaler and compare mode, One 16-bit counter with Separate Prescaler,compare mode and capture mode.

#ARDUINO UNO PINOUT DATASHEET SERIAL#

Master/Slave SPI Serial Interface(17,18,19 PINS) SDA (Two-wire Serial Bus Data Input/output Line) This is the clock shared between this controller and other system for accurate data transfer. When controller acts as slave, the data is sent to master by this controller through this pin. OC2 (Timer/Counter2 Output Compare Match Output) When controller acts as slave, the data is received by this pin.

OC1B (Timer/Counter1 Output Compare Match B Output) This pin is low when controller acts as slave. OC1A (Timer/Counter1 Output Compare Match A Output) The divided system clock can be output on the PB0 pin) OC0A(PWM - Timer/Counter0 Output Compare Match A Output)ĬLKO (Divided System Clock. OC0B(PWM - Timer/Counter0 Output Compare Match B Output) XTAL1 (Chip Clock Oscillator pin 1 or External clock input) OC2B(PWM - Timer/Counter2 Output Compare Match B Output) PC6 can only be used as I/O pin when RSTDISBL Fuse is programmed. We will describe functions of each pin in below table. Many pins of the chip here have more than one function. It is the most popular of all AVR controllers as it is used in ARDUINO boards.ĪTMEGA328P is a 28 pin chip as shown in pin diagram above. ATMEGA328P is an 8-bit microcontroller based on AVR RISC architecture. ATMEGA328P is high performance, low power controller from Microchip.
