Atmel ATmega328P-PU – AVR microcontroller in a DIP-28 package

The ATmega328P-PU is an 8-bit microcontroller from the AVR family, best known as the heart of Arduino Uno boards. The DIP package with 28 pins lets you seat it in a socket on a universal or prototype board without SMD soldering.

Capabilities

• 32 KB Flash program memory,
• 2 KB RAM and 1 KB EEPROM,
• 23 input/output lines,
• 6 ADC inputs and 6 PWM channels,
• three timers,
• I2C, SPI and UART interfaces.

Power and operation

The chip operates in a voltage range of 1.8 to 5.5 V and a temperature range of -40 to +85 degrees Celsius. It can use an internal or external oscillator, and the maximum clock frequency according to the description is 20 MHz.

Applications

The microcontroller works well in your own electronics projects, sensors, lighting controllers, simple robots and learning to program embedded systems. It can replace a damaged chip on an Arduino-compatible board or be used to build a minimal system on a breadboard. Keep in mind that a unit may require a bootloader to be uploaded.

Specifications

This ATmega328P-PU microcontroller in a DIP-28 package is a sensible choice for anyone who wants to build their own integrated circuit controlling a device.
