Overview

The ATMEGA328P-MUR is a high-performance, low-power 8-bit AVR RISC-based microcontroller featuring 32KB ISP flash memory, 1KB EEPROM, and 2KB SRAM. This variant comes in a space-saving 32-pin VQFN package and supports operating frequencies up to 20MHz at industrial temperature ranges.

Why Choose This Part

It offers an excellent balance between performance and power consumption with a wide 1.8V to 5.5V operating range. The massive community support and extensive library availability through the AVR architecture significantly reduce development time.

Applications

Arduino-Compatible Development

Serving as the core processor for the Arduino Uno and Nano ecosystems, it is ideal for rapid prototyping and educational projects.

Industrial Sensor Nodes

Utilizing the integrated 10-bit ADC and low-power sleep modes for remote monitoring and data logging.

Battery-Powered Handhelds

Leveraging picoPower technology to extend battery life in portable consumer devices and instrumentation.

Motor Control and PWM

Using six PWM channels to manage small DC motors, servos, or LED dimming applications.

Getting Started

Developers can use the Microchip Studio IDE or the Arduino IDE for software development. Hardware debugging and programming are typically performed using an Atmel-ICE or an AVRISP mkII programmer via the ICSP or debugWIRE interfaces.
