ATmega328P: 8‑bit AVR Microcontroller for Precision Control

The ATmega328P is a versatile, low‑power 8‑bit AVR microcontroller designed for embedded systems requiring reliable performance and rich peripheral support. It features a Harvard architecture core, real‑time interrupt handling, and integrated EEPROM, making it ideal for applications ranging from hobbyist projects to industrial automation.

Equipped with up to 32 kB Flash, 2 kB SRAM, and 1 kB EEPROM, the ATmega328P delivers ample memory for complex firmware while keeping the footprint small. Its operating voltage spans 1.8 V to 5.5 V, and it supports clock frequencies up to 20 MHz, providing a flexible balance between speed and power efficiency. The 28‑pin LQFP package offers 23 general‑purpose I/O pins, multiple UART, SPI, I²C interfaces, and a dedicated 10‑bit ADC, enabling comprehensive sensor interfacing and serial communication.
