The ATmega328P-PU is a low-power, high-performance 8-bit CMOS microcontroller based on Atmel’s enhanced AVR RISC architecture. It executes powerful instructions in a single clock cycle, achieving up to 1 MIPS per MHz, allowing designers to strike an optimal balance between processing speed and power efficiency.
Featuring a rich instruction set and 32 general-purpose working registers, all directly connected to the Arithmetic Logic Unit (ALU), the ATmega328P-PU enables efficient code execution. This architecture allows two registers to be accessed simultaneously in a single clock cycle, delivering throughput up to ten times faster than traditional CISC microcontrollers.
The ATmega328P-PU is supported by a complete suite of development tools, including C compilers, macro assemblers, debuggers/simulators, in-circuit emulators, and evaluation kits, making it ideal for a wide range of embedded applications.
