The ATMEGA329A-AUR is a low-power AVR 8-bit microcontroller from Microchip Technology in a 64-TQFP package. It operates from 1.8V to 5.5V at speeds up to 20MHz, with 32KB of flash and 2KB of RAM. A key feature is its integrated LCD controller, along with PWM, Brown-out Detect/Reset, POR, and WDT, making it ideal for portable and display-centric applications.
- Integrated LCD controller: Eliminates external display driver ICs, reducing cost and PCB space.
- Ultra-low 1.8V operation: Extends battery life in portable devices using single-cell batteries.
- High-speed 20MHz AVR core: Provides ample processing power for UI and communication tasks.
- 64-pin TQFP: Offers abundant I/O for interfacing with sensors, keypads, and external memory.
Portable Medical Displays
The integrated LCD driver directly controls segmented displays for glucose meters or blood pressure monitors, while the 1.8V operation extends battery life.
Smart Utility Meters
With 32KB flash and LCD support, it can manage multi-rate tariff calculations and display consumption data on a built-in LCD panel.
Wearable Fitness Trackers
The 1.8V minimum supply allows operation from a single lithium coin cell, and the 20MHz speed handles sensor fusion algorithms.
Home Automation Keypads
Its LCD driver and PWM outputs enable backlit touch interfaces for smart thermostats or security panels.
Industrial Panel Meters
The 64-TQFP package provides enough I/O for reading rotary encoders and driving a 7-segment LCD in harsh factory environments.
Battery-Powered Data Loggers
Low-voltage operation and WDT ensure reliable long-term logging in remote environmental monitoring stations.
