The microchip or integrated circuit invention is one of the greatest discoveries. Thus, the majority of modern products today use microchip technology. One such example is the ATMega328P. This article will help you understand how to use ATMEGA328P, its various features, pin configuration, and various areas of application.
What is an ATMega328P?
The ATMega328P is a single-chip microcontroller commonly used in Arduino products. It has a high performance and consumes low power, thus executing approximately 131 instructions.
In brief, the high performance is due to its advanced Reduced Instruction Set Computer architecture (RISC). Thus, the microcontroller is effective in systems or devices that require low power and cost microcontrollers.
ATMega328P Pin Configuration
ATMega328P has 28 pins, where each pin serves various secondary functions. Below is a description of what each pin does.
Then, its clock speed stands at 16 MegaHertz, and it has a total of 14 I/O pins.
Third, it operates at a minimum temperature of 40 degrees centigrade and a maximum temperature of 105 degrees centigrade.
Fourth, it has two eight-bit and sixteen-bit timers.
Also, it’s an advanced RISC with 6 Pulse Width Modulation PWM) channels.
Lastly, it operates at a minimum voltage of 1.8 D.C and a maximum of 5.5.
How to use the ATMega328P
As you’d expect, the ATMega328P is just like any other microcontroller. First, it is necessary to program the controller by incorporating the right program in the controller’s Flash memory.
After writing the program, the controller runs the code to get the right response.
