arduino uno circuit diagram altium atmega328p datasheet

ATmega-328 is an AVR Microcontroller having twenty-eight (28) pins in total.

The following table shows the complete features of ATmega328:.

You should have a look at these Real Life Examples of Embedded Systems, we can design all of them using this Microcontroller.

It's normally used in Embedded Systems applications.

Its excellent features include cost-efficiency, low power dissipation, programming lock for security purposes, real timer counter with separate oscillator.

It operates ranging from 3.3V to 5.5V but normally we use 5V as a standard.

You must have heard of Arduino UNO, UNO is based on atmega328 Microcontroller.

It also has 3 built-in Timers, two of them are 8 Bit timers while the third one is 16-Bit Timer.

It has 8 Pins for ADC operations, which all combine to form PortA ( PA0 - PA7 ).

It has an EEPROM memory of 1KB and its SRAM memory is 2KB.

Atmega328 is the microcontroller, used in basic Arduino boards i.e Arduino UNO, Arduino Pro Mini and Arduino Nano.

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

Moreover, I have also given the link to a reliable online source from where you can buy it easily.ĭownload Atmega328P Datasheet Introduction to ATmega328.

Here's the link to download the Atmega328 datasheet, although after reading this article you won't need it.

Further details about ATmega 328 will be given later in this section. These features consist of advanced RISC architecture, good performance, low power consumption, real timer counter having separate oscillator, 6 PWM pins, programmable Serial USART, programming lock for software security, throughput up to 20 MIPS etc.

ATmega 328 has several different features which make it the most popular device in today's market. Other characteristics will be explained later. Moreover, ATmega-328 has 2KB Static Random Access Memory (SRAM). This property shows if the electric supply supplied to the micro-controller is removed, even then it can store the data and can provide results after providing it with the electric supply. ATmega-328 has 32KB internal flash memory.ĪTmega328 has 1KB Electrically Erasable Programmable Read-Only Memory (EEPROM). Today, I am going to give you a detailed Introduction to ATmega328. ATmega328 is an Advanced Virtual RISC (AVR) microcontroller. Hello everyone! I hope you all will be absolutely fine and having fun.
