ATMEGA328P-AU Part Information
The high-performance Microchip picoPower 8-bit AVR RISC-based microcontroller combines 32KB ISP flash memory with read-while-write capabilities, 1024B EEPROM, 2KB SRAM, 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. The device operates between 1.8-5.5 volts. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.

In many a business, one product defines a legacy - for PSC Tupolev, this would be the legendary TU134. In the case of Atmel - initially a small European microcontroller company claiming to offer a C-programmable microcontroller, this honor falls to the ATmega328.
Describing the ATmega328 is not easy - it is, in the end, but another microcontroller similar to the various members of the PIC family. An amusing detail is that Atmel is now owned by Microchip - sometimes, fate takes the oldest turns.
Nevertheless, the ATmega328 is a highly interesting microcontroller due to another twist of history. When Massimo Banzi, Godfather of Arduino, looked for a microcontroller he settled on the ATmega328.
This means that developers can look forward to an almost unlimited amount of libraries - if you must get started quickly, this is a part to use for rapid prototyping. Of course, it also is available in prototype friendly DIP housing, make it ideally suited for Internet of Things prototype microcontroller duties.
