Atmega328 pins

Atmega328 has 28 pins in total. It has 3 Ports in total which are named as Port B, Port C and Port D. Port C is an analogue Port and it has six pins in total. So, in simple words, ATmega328 has 6 analogue pins.

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 the maximum I O pins for ATmega328?

Parameter	Value
EEPROM	1 KB
Package pin count	28 or 32
Capacitive touch sensing channels	16
Maximum I/O pins	23

How many pins are there in ATmega328 microcontroller IC?

ATmega328 is an 8-bit, 28-Pin AVR Microcontroller, manufactured by Microchip, follows RISC Architecture and has a flash-type program memory of 32KB.

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.

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.

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).

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 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 you program ATmega328?

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"

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.

What is the full form of MOSI pin in ATmega328?

MOSI (Master Output Slave Input). When controller acts as slave, the data is received by this pin. [

How many ports are in Arduino Uno 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 many pins are there in Arduino Uno?

Arduino UNO is a microcontroller board based on the ATmega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header and a reset button.

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.

What are the features of ATmega328?

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.
