What is the maximum I O pins for ATMEGA328P?

What is the maximum I O pins for ATMEGA328P?

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….Features.

Parameter Value
Maximum I/O pins 23
External interrupts 2
USB interface No

Which pins in the ATMEGA328P microcontroller supports for ADC?

It has an EEPROM memory of 1KB and its SRAM memory is 2KB. It has 8 Pins for ADC operations, which all combine to form PortA ( PA0 – PA7 ).


Typically there are three lines common to all the devices: MISO (Master In Slave Out) – The Slave line for sending data to the master, MOSI (Master Out Slave In) – The Master line for sending data to the peripherals, SCK (Serial Clock) – The clock pulses which synchronize data transmission generated by the master.

How many of the ATMEGA328P pins can be used as general purpose digital input output pins?

This microcontroller has three digital ports (B, C, D) such as PORTB, PORTC, and PORTD. All these pins can be used as digital input/output. On top of that, each port can be used for other purposes.

How many pins of Atmega328 are accepted interrupts?

These 23 pins are divided into three (3) interrupt groups (PCI 2:0) of eight (8), seven (7) and (8). Consequently to enable and individual pin change interrupt 3 interrupt mask bits must be set to one (1). The pin change interrupt enable bit (PCIE 2:0) group the pin is assigned.

Does Mosi go to Miso?

MOSI and MISO are the data lines. MOSI transmits data from the master to the slave and MISO transmits data from the slave to the master.

How do you code ATMEGA328P?

From the Tools menu, under Board:, select Arduino Nano. Then, in Tools > Programmer: select USBasp. From the Tools menu, under Programmer:, select USBasp. Now, to flash the Arduino bootloader onto the ATmega328p, we first need to connect the USB ASP programmer to the Maker Pro robot PCB.

Why ATmega328p is used in Arduino?

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 should I know about ATmega328P pin configuration?

ATmega328P is a high performance microcontroller chip. Today we are going discuss its pinout diagram or pin configuration, uses, description, datasheet and other details on how to use this microcontroller. Minimum & maximum temperature -40 degree centigrade to 105 degree centigrade

What is internal clock speed of Arduino ATmega328P?

As stated in the name, the configuration we just loaded into the Arduino IDE (ATmega328 on a breadboard (8 MHz internal clock)), assumes that the internal clock speed of the ATmega328P is set to 8MHz. While 8MHz is one of the clock speeds of the microcontroller, it is likely not operating at that speed.

Is the ATMega32 microcontroller an AVR controller?

ATMEGA32 is easy to program AVR controller. With appreciable program memory it can satisfy most EMBEDDED SYSTEMS. With various sleep modes it can work on MOBILE EMBEDDED SYSTEMS. Along with 32 programmable Input/Output pins, it can interface many peripherals easily.

Is there a plug and play digital IC for ATMega32?

Similar to them it is not Plug and Play digital ICs. For working of ATMEGA32, first we need to save the appropriate program file in the ATMEGA32 FLASH memory. After dumping this program code, the controller executes this code to create the response. After writing the desired program compile for error elimination using IDE.
