The ATmega328P-PU DIP-28 Microcontroller IC is the genuine 8-bit AVR chip that powers the Arduino Uno and countless other AVR-based boards, supplied in the classic through-hole DIP-28 package for breadboard and socket use. It pairs a fast RISC core with generous onboard memory, making it a popular standalone brain for custom circuits and Arduino board replacements.
Key Features:
- Microcontroller: ATmega328P 8-bit AVR RISC core delivering up to 20 MIPS at 20 MHz.
- Operating Voltage: Runs from 1.8V to 5.5V, compatible with both 3.3V and 5V circuits.
- Flash Memory: 32 KB of in-system programmable flash for storing sketches and firmware.
- SRAM and EEPROM: 2 KB SRAM plus 1 KB EEPROM for persistent data storage.
- DIP-28 Package: Standard 0.3-inch wide through-hole package fits any breadboard or 28-pin IC socket.
- Rich Peripheral Set: Includes UART, SPI, I2C, a 6-channel 10-bit ADC and multiple PWM-capable timers.
Package Includes:
- 1 x ATmega328P-PU DIP-28 IC
