The Microchip ATMEGA808-MFR is an 8-bit AVR microcontroller with 8KB flash and 1KB SRAM. It operates from 1.8V to 5.5V at up to 20MHz, featuring brown-out detection, power-on reset, and a watchdog timer. Housed in a 32-VFQFN package, it is designed for reliable operation from -40°C to 125°C, making it ideal for industrial and automotive applications.
- Wide voltage range (1.8V-5.5V) – simplifies power supply design and supports battery operation.
- High-temperature rating (125°C) – enables use in engine bays and industrial ovens.
- Integrated brown-out and watchdog – improves system reliability without external components.
- Compact 32-VFQFN package – saves PCB space for dense designs.
Battery-Powered Sensor Nodes
The 1.8V minimum supply and low-power sleep modes enable long-life operation in IoT sensors.
Industrial Control Panels
With a 125°C junction temperature rating and 20MHz throughput, it handles real-time control loops in harsh environments.
Automotive Body Electronics
Brown-out detection and POR ensure reliable reset behavior during cranking voltage dips.
Portable Medical Devices
The 8KB flash and 1KB SRAM are sufficient for monitoring algorithms while maintaining small form factor.
Smart Home Hubs
Multiple communication protocols can be implemented using the flexible I/O and timers.
LED Lighting Controllers
PWM outputs and 20MHz speed allow smooth dimming and color mixing.
