ATtiny45 is a small-size microcontroller available in 8-pin dip and other packages. It is the latest design microcontroller & it contains a variety of built-in features which are not available in that size and kind of microcontroller previously. The internal design is built to obtain very less power which makes it ideal for battery-operated, solar-powered, and portable devices. It can also be used to shrink small Arduino projects. However, the user must note that it cannot perform as the ATmega328p because due to its size and design it contains less flash memory, EEPROM, and SRAM but if the program code comes under these limits then you are ready to go. Moreover, the 4 kilobytes of flash memory 256 bytes of SRAM & 256 bytes of EEPROM are quite enough to run a variety of programs that you run on ATmega328p. For example, you can attach sensors, send data, and almost any simple task that you perform with Arduino.
