Description
This ATmega328P is a 28-pin DIP microcontroller IC pre-flashed with the Arduino Uno R3 Optiboot bootloader. It enables you to drop the processor directly into breadboards or custom PCBs without needing a dedicated external programmer. It is ideal for students, hobbyists, and makers building standalone Arduino-compatible circuits.
Pre-loaded bootloader
The IC is supplied with the Arduino Uno R3 Optiboot bootloader already installed, making it ready for direct use in compatible boards and DIY embedded designs.
Memory and performance
Featuring 32 KB of program memory, 2 KB SRAM, and 1 KB EEPROM, this 28-pin DIP chip operates at speeds up to 20 MHz within a 1.8 V to 5.5 V supply range.
Peripherals and communication
The microcontroller includes six PWM channels, a 6-channel 10-bit ADC, programmable serial USART, master/slave SPI, and an I2C-compatible interface. It also provides three hardware timer/counters, an on-chip analog comparator, and a real-time clock with a separate oscillator.
