This microcontroller is an ATmega328P-U PDIP-28.
This is the ATmega328P-PU IC, often referred to as ATmega328P-U, in Chinese. Thus, an IC with the printed name ATmega328P-U may be sent to you.
AVR improved RISC architecture serves as the foundation for the low-power CMOS 8-bit microcontroller, the ATMEGA328P-U. The ATmega328P-PU achieves throughputs of about 1 MIPS per MHz by carrying out complex instructions in a single clock cycle, which enables the system designer to balance processing speed and power consumption.

32 general purpose working registers and a robust instruction set are combined in the AVR core. Since the Arithmetic Logic Unit (ALU) is directly coupled to all 32 registers, one instruction can access two separate registers in a single clock cycle. In comparison to traditional CISC microcontrollers, the new design achieves throughputs up to ten times quicker while being more code efficient.
A comprehensive range of tools for developing programmes and systems, such as C compilers, macro assemblers, programme debugger/simulators, in-circuit emulators, and evaluation kits, are available for the ATmega328P-PU AVR.

Note: The available IC model for this type is ATMEGA328P U.
