ATMEGA328P-PU Information

Description

The ATmega328P-PU is an 8-bit AVR microcontroller from Microchip (formerly Atmel). It features 32KB of Flash memory, 1KB of EEPROM, and 2KB of SRAM. The device operates at a clock frequency of up to 20 MHz and supports various communication protocols such as SPI, I2C, and UART. The ATmega328P-PU is widely used in embedded systems applications due to its versatility and affordability. It finds extensive use in projects such as robotics, automation, IoT devices, sensor interfaces, and educational platforms like Arduino. Its features, including analog-to-digital conversion, PWM, and numerous I/O pins, make it suitable for a wide range of projects requiring embedded control and processing. The ATmega328P-PU is available in a 28-pin dual-in-line package (DIP) with a 7.62 mm row pitch. It is an excellent choice for beginners and experienced developers alike, offering a great balance between performance, power consumption, and cost.
