Description
📌 Product Overview: ATmega328P-AU Microcontroller (TQFP-32)
The ATmega328P-AU is a high-performance, low-power 8-bit AVR microcontroller based on the AVR enhanced RISC architecture. Manufactured by Microchip Technology (formerly Atmel), it offers a balanced combination of processing power, low power consumption, and rich peripheral features—ideal for embedded systems, Arduino boards (e.g., Uno), and custom compact designs.
The “AU” suffix indicates the TQFP-32 package, making it surface-mountable for compact PCB layouts.
