Atmega328p

ATmega328P is a high performance yet low power consumption 8-bit AVR microcontroller that's able to achieve the most single clock cycle execution of 131 powerful instructions thanks to its advanced RISC architecture. It can commonly be found as a processor in Arduino boards such as Arduino Fio and Arduino Uno.

What is P in ATmega328P stand for?

BJustification: The p letter in ATmega328p stands for pico‐power5.

Is ATmega328P discontinued?

Introduction. This ATmega328 chip is Discontinued Now, We recommend another ATmega328 Chip with Arduino Bootloader as a suitable replacement.

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.

Is ATmega328 a microcontroller?

The ATmega328 is a single-chip microcontroller created by Atmel in the megaAVR family (later Microchip Technology acquired Atmel in 2016). It has a modified Harvard architecture 8-bit RISC processor core.

Is ATmega328 a CPU?

Created by Atmel, the ATmega328P is a single-chip microcontroller based on an 8-bit RISC processor core.

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.

How much RAM does Atmega328P have?

RAM is limited to 2 Kbyte on an ATmega328, and often a scarce resource, especially since all strings also need to stored there (these get copied from flash on startup). EEPROM memory is the “configurable” memory available to a sketch.

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.

Can we use ATmega328 without Arduino?

You can use arduino board with the IC. Program the IC and then take it out and use it in your circuit. You will have to use 16MHZ Oscillator with capacitors. If you don't have arduino board, you can use other programmers like USBasp to program your Atmega328p .

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.

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.

Which software used for ATmega328P?

Download and install WinAVR from this page. WinAVR is a full suite with a compiler, programmer, debugger, and more! Use these for the USBTiny. It will include Programmer's Notepad, which is what we are going to use to program the ATMega, the AVRDude, and will burn fuses and act as a backup for programming the ATMega.

Which Arduino is most powerful?

The official basic model is the Arduino Uno, which is a perfect introduction to this exciting world. However, if you want more power, you can go for the Arduino Zero. Or if you prefer something with as many inputs as possible, then the Arduino Mega, which comes with 54 digital inputs, maybe for you.

How is ATmega328 programmed?

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"

Why ATmega328 is used in Arduino Uno?

Communication. The Arduino/Genuino Uno has a number of facilities for communicating with a computer, another Arduino/Genuino board, or other microcontrollers. The ATmega328 provides UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX).

Can ATmega328 work without crystal?

Everybody runs the ATMega328 without a 16mhz crystal. Most people do use a 16MHz crystal.

What does 328 mean in ATmega328?

ATmega328 Pins ATmega-328 is an AVR Microcontroller having twenty-eight (28) pins in total. All of the pins in chronological order, are listed in the table shown in the figure given below.

Is ATmega328 an AVR?

Microchip Technology ATmega328 8-Bit AVR MCUs are low-power, CMOS 8-bit microcontrollers based on the AVR® enhanced RISC architecture. The devices execute instructions in a single clock cycle to achieve CPU throughput approaching one million instructions per second (MIPS) per megahertz.

Does ATmega328 have UART?

The Universal Asynchronous Receiver and Transmitter (UART) capability of the Atmega328P allows you to easily comminicate with your microcontroller from your PC. In addition, it is the primary interface to many other devices, such as GPS receivers.
