Atmega328P-PU DIP IC
The ATmega328P-PU is a high-performance 8-bit AVR microcontroller from Microchip, widely used in embedded systems and electronics prototyping. Housed in a DIP-28 (Dual Inline Package) form, it’s breadboard-friendly and ideal for quick development without needing surface-mount soldering.
This microcontroller features a robust RISC-based architecture with 32KB of programmable Flash memory, 1KB EEPROM for persistent data, and 2KB SRAM. Operating at clock speeds up to 20 MHz, it offers balanced performance and energy efficiency, making it a go-to choice for both commercial and educational electronics.
It supports multiple communication protocols including UART, SPI, and I²C, along with 6 PWM channels, timers, and an 8-channel 10-bit ADC — enabling rich peripheral interfacing and signal processing.
