ATMEGA328P TQFP 32 Pin Microcontroller SMD Package

ATMEGA328P TQFP 32 Pin Microcontroller SMD Package 

The ATmega328P is a high-performance 8-bit AVR microcontroller developed by Atmel (now Microchip Technology). It is one of the most widely used AVR controllers and is the core MCU of the Arduino Uno.

The microcontroller is based on Harvard architecture with a RISC instruction set, enabling most instructions to execute in one clock cycle. The “P” suffix denotes picoPower technology, which provides low power consumption, making it suitable for battery-operated and energy-efficient systems.

The TQFP-32 surface-mount package offers a compact footprint, more ADC channels, and is ideal for modern PCB designs.
