ATmega328P-PU Microcontroller

ATmega328P Microcontroller is the most widely used standalone Atmega IC for electronics projects. It can be connected to an Atmega328 board as a replacement for an Arduino. However, if you are planning to replace the Arduino chip then we can provide you Atmega328p with the Arduino bootloader. 

This microcontroller does not come with the bootloader pre-installed.

It is a low power CMOS 8-bit micro controller based on the AVR enhanced RISC architecture. It has 32 KB ISP flash memory with read-while-write capabilities, 1 KB EEPROM, internal and external interrupt, 2 KB SRAM, 6 channel 10 Bit A/D converter, 23 General purpose IO lines, 32 general purpose working registers, 3 flexible timer/counter with compare modes, serial programmable USART, a byte oriented 2 wire serial interface, SPI serial port, programmable watchdog timer with internal oscillator and 5 software selectable power saving modes.

The Atmega328 offers 8-bit PWM, 10-bit 6 channel ADC, I2C, SPI, Digital I/O pins and UART, all in one in a single microcontroller unit. 

Atmega328 also has 32 KB of flash memory for storing code (of which 0,5 KB is used for the bootloader); It has also 2 KB of SRAM and 1 KB of EEPROM.
