ATMega328P AVR Microcontroller

ATMega328P AVR Microcontroller — 8-Bit Arduino MCU

The ATMega328P is the heart of the Arduino Uno, a high-performance low-power 8-bit AVR microcontroller from Microchip (formerly Atmel). With 32KB flash, 2KB SRAM, 6-channel 10-bit ADC, USART, SPI, and I2C, it is one of the most widely used MCUs in embedded systems and maker projects worldwide.

Key Features

• 32KB ISP Flash with Read-While-Write capability
• 2KB SRAM, 1KB EEPROM
• 23 general-purpose I/O lines
• 6-channel 10-bit ADC
• 3 Timer/Counters with PWM
• USART, SPI, I2C interfaces
• Real-Time Counter (RTC)
• 6 power-saving modes
• 28-pin DIP / 32-pin TQFP package

Applications

• Arduino Uno and compatible boards
• Embedded control and automation
• IoT sensor nodes
• Educational and prototyping projects
