The Microchip ATMEGA809-MU is an 8-bit AVR microcontroller with a 20MHz core, 8KB Flash, and 1KB SRAM. It operates from 1.8V to 5.5V and is housed in a 48-VFQFN package. Integrated features include PWM, Brown-out Reset, POR, and WDT, making it a versatile choice for industrial and consumer control applications.
- Wide voltage range (1.8V-5.5V): Simplifies design in mixed-voltage environments.
- High I/O count: 48-pin package provides ample GPIO for complex interfaces.
- 20MHz AVR core: Fast execution for real-time control loops.
- Integrated safety features: Brown-out Detect and WDT improve system reliability.
- Cost-effective: 8KB Flash balances memory and price for mid-range applications.
Industrial Automation Controllers
The 5.5V capability and 20MHz speed allow direct interfacing with industrial sensors and actuators without level shifters.
Automotive Body Electronics
With a wide temperature range and robust reset circuitry, it suits door modules, window lifters, and lighting control.
Smart Appliances
8KB Flash is sufficient for motor control algorithms with PWM, enabling efficient washing machines or fans.
Building Management Systems
Multiple PWM channels can drive HVAC valves or dimmable lighting, while WDT ensures failsafe operation.
Consumer Robotics
The 48-pin package provides ample I/O for servo control and sensor fusion in hobby or educational robots.
Power Tools
High voltage tolerance and 20MHz processing handle brushless DC motor commutation in cordless drills.
