ATmega328P-PU microcontroller is used in Arduino Uno, and can be used to create an Arduino circuit on a breadboard.
The high-performance Atmel picoPower 8-bit AVR RISC-based microcontroller combines 32KB ISP flash memory with read-while-write capabilities, 23 general purpose I/O lines, 32 general purpose working registers, three flexible timer/counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented 2-wire serial interface, SPI serial port, a 6-channel 10-bit A/D converter (8-channels in TQFP and QFN/MLF packages), programmable watchdog timer with internal oscillator, and five software selectable power saving modes. Atmega328P-PU has wide operating voltage and 20 MIPS speed using external crystal.
This microcontroller is not bootloaded with the arduino bootloader.
