ATMEGA328PU microcontroller DIP28 package

the atmega328 microcontroller is an 8-bit microcontroller from the atmega series of atmel, which is very similar to the atmega168, but with the difference that its flash memory is twice as much, meaning it has 32 kilobytes of space for code storage and has 32 input/output lines and a processing speed of up to 20 megahertz using an external crystal. this ic is one of the low-power ics made with cmos technology and based on the avr structure with a powerful risc architecture. the operating voltage of the microcontroller is between 1.8 to 5 volts. the processor core of this ic is 8-bit and has a working frequency of 20 megahertz. this microcontroller is very economical and is used in various applications, and it can be used in the construction of arduino boards, embedded projects, robotics, and power monitoring.
