Description:
The ATMega328-PU ATmel Microcontroller IC – Pack of 2 offers the robust performance of the 8-bit AVR architecture in a standard 28-pin DIP package. This microcontroller is at the heart of many popular Arduino boards, including the Uno, and is widely appreciated for its balance of power, simplicity, and flexibility. It comes preloaded with the Arduino bootloader, making it ideal for custom Arduino-compatible development boards or standalone embedded applications.
Each microcontroller features 32 KB of flash memory, 1 KB of EEPROM, and 2 KB of SRAM, along with 23 programmable I/O lines. Additionally, it supports multiple communication protocols including SPI, I2C, and USART, plus features like timers, PWM, and a 10-bit ADC with six channels. With a maximum clock speed of 20 MHz and an operating voltage range from 1.8V to 5.5V, the ATMega328-PU is both power-efficient and versatile—perfect for robotics, data logging, sensor systems, and IoT applications.
