The ATMEGA4809-MUR from Microchip Technology is a powerful 8-bit AVR MCU with 48KB flash and 6KB SRAM. Running at 20MHz, it operates from 1.8V to 5.5V and includes PWM, WDT, POR, and brown-out detection. The 48-UFQFN package is designed for high-density industrial and IoT applications.
- Large memory (48KB flash, 6KB SRAM): Supports complex applications and data buffering.
- 20MHz AVR core: Efficient execution for real-time control and communication.
- Wide voltage range (1.8-5.5V): Flexible for battery or 5V logic systems.
- Compact QFN48 package: Ideal for space-constrained, high-pin-count designs.
Industrial Automation Controllers
The 48KB flash and 6KB RAM allow complex state machines and Modbus stacks, while the 20MHz AVR core handles fast I/O.
Smart Home Hubs
With 6KB RAM, it can buffer sensor data and run Zigbee or Thread protocol stacks, with the QFN48 package fitting compact hub PCBs.
Robotics Control Boards
Multiple PWM channels and 20MHz speed enable servo control and sensor fusion for hobby and educational robots.
Data Logging Systems
Large memory capacity supports circular buffers for environmental monitoring, with low-power modes for field deployment.
Medical Device Interfaces
The 1.8-5.5V range and robust peripherals make it suitable for portable diagnostic tools requiring reliable operation.
Automotive Body Electronics
With BOD and WDT, it handles window lift or mirror control, with the exposed pad aiding thermal dissipation.
