Microchip Technology
AVR AVR® ATmega Microcontroller IC 8-Bit 20MHz 32KB (16K x 16) FLASH 44-VQFN (7x7)
NRND8,765 in stock

Overview

The ATMEGA324PA-MUR is a high-performance, low-power 8-bit AVR RISC-based microcontroller featuring 32KB of ISP Flash memory and 2KB of SRAM. This variant is housed in a compact 44-VQFN package and supports clock speeds up to 20MHz, making it suitable for space-constrained embedded designs that require efficient processing.

Why Choose This Part

This MCU features an on-chip 2-cycle multiplier and 131 instructions for efficient code execution. Its PicoPower architecture ensures low power consumption in active and sleep modes, while the 44-pin VQFN package provides a high I/O-to-footprint ratio for dense PCB layouts.

Applications

Battery-Powered Sensors
Utilizes PicoPower technology with a 0.6uA sleep mode to extend life in remote monitoring applications.
Industrial Control Interfaces
Leverages 32 I/O lines and integrated PWM for managing human-machine interfaces and motor drivers.
Handheld Instrumentation
Combines 1024 bytes of EEPROM for persistent calibration data with dual USARTs for peripheral communication.
