  • Information

The ATMEGA328P-PN is a popular microcontroller due to it being a major component in the Arduino board products. The ATMEGA328P-PN is the 8-bit RISC heart of the Arduino Uno and Nano, with a maximum clock frequency of 20MHz, 32KB program FLASH, and 2KB of RAM. The ATMEGA328P-PN contains many on-board peripherals, including UART, SPI, timers, ADC, comparators, and a watchdog, and is housed in a 28-DIP package which enables designers to easily prototype their designs before committing to surface mount technology. With a temperature range of -40°C to 105°C and voltage range of 1.8V to 5.5V, the ATMEGA328 truly is a versatile, cost-effective microcontroller.

Evaluation Board

Evaluation boards are available for the ATMEGA328, with the most practical option being the Arduino Uno. Programmed via a standard USB connector, the Uno integrates the ATMEGA328 onto a board with I/O headers to provide an easy-to-use platform for programming the ATMEGA328. The on-board microcontroller includes a bootloader for enabling programming over UART. Library support for the Arduino Uno is arguably one of the largest available and includes servo control, I2C, displays. and even Wi-Fi bridges.
