Greetings all,
ATMEGA328P has to be one of the most popular microcontrollers on the market. Why so? Well this microcontroller is apart of the Arduino Uno which is a popular board of the Arduino lineup. In my opinion, I think starting with the learning of this exact chip is the way to go so you can learn what's the brain of the Arduino. Honestly, the board itself cannot function without the microcontroller so it's a must to learn. What's even better is that you can create projects without having the Arduino at all. Doing so will advance your projects in the world of Bare Metal. That's another topic, but don't worry. In the future you will learn more for I will drop those blog posts lol.Well... let's get deeper into the ATMEGA328P.
Before diving into the micro-controllers, let's speak briefly about the company that makes the ATMEGA328P. ATMEL is a company that created a family of micro-controllers called: AVR. AVR (Advanced Virtual RISC) micro-controllers primary focus is to be the "brain" of the electronic device like stated prior. After years of work, they decided to sell the company to Microchip later making what we see today. The primary focus is to provide control of the electronic device. For more insights about the company you can visit their website here: Microchip.
Key Features of the ATMEGA328P:
Processor: 8-bit
Clock Speed: Up to 20MHz
Flash Memory: 32KB
SRAM: 2KB internal
EEPROM: 1KB of internal
Here is the pinout of the ATMEGA328P. This is crucial because it shows the physical layout and assignment of the pins. The datasheet of a micro-controller is also very important and I highly advise you looking at it. Information about the features, memory and how it can be used in apps are all there. When getting in the habit of reading datasheets and pinouts, you can take your projects to the next level. Believe me.
Welp that's about all for this great micro-controller review. Take a moment to read about other AVR chips such as ATTiny85 and the ATMega16U. These are also incredible and I plan to use in the near future for projects.
Until next post...
-Odot!
