The ATmega328P is a low power, CMOS 8-bit microcontrollers based on the AVR® enhanced RISC architecture. By executing instructions in a single clock cycle, the devices achieve CPU throughput approaching one million instructions per second (MIPS) per megahertz, allowing the system designer to optimize power consumption versus processing speed.

ATMEGA8535,ATMEGA16, ATMEGA32,
Although we have many controllers ATMEGA328P is most popular of all because of its features and cost. ARDUINO boards are also developed on this controller because of its features.
With program memory of 32 Kbytes ATMEGA328P applications are many.
With various POWER SAVING modes it can work on MOBILE EMBEDDED SYSTEMS.
With Watchdog timer to reset under error it can be used on systems with minimal human interference.
With advanced RISC architecture, the controller executes programs quickly.
Also with in chip temperature sensor the controller can be used at extreme temperatures.
ATMEGA328P is used similar to any other controller. All there to do is programming.First, we need to program the controller and that is done by writing the appropriate program file in the FLASH memory. After dumping this program code, the controller executes this code and provides appropriate response.
Entire process of using an ATMEGA328 is as followed:
List the functions to be executed by controller.
Write the functions in programming language in IDE programs.
ATMEGA328P programming can also be done in ARDUINO IDE.
After writing the program, compile it to eliminate errors.
Make the IDE generate HEX file for the written program after compiling.
This HEX file contains the machine code which should be written in controller flash memory.
Choose the programming device (usually SPI programmer made for AVR controllers) which establishes communication between PC and ATMEGA328P. You can also program ATMEGA328P using ARDUINO UNO board.
Run the programmer software and choose the appropriate hex file.
Burn the HEX file of written program in ATMEGA328P flash memory using this program.
Disconnect the programmer, connect the appropriate peripherals for the controller and get the system started.
Used in ARDUINO UNO, ARDUINO NANO and ARDUINO MICRO boards.
Industrial control systems.
SMPS and Power Regulation systems.
Digital data processing.
Analog signal measuring and manipulations.
Embedded systems like coffee machine, vending machine.
Motor control systems.
Display units.
Peripheral Interface system.
