The Microchip ATMEGA4808-MFR is a high-temperature 8-bit AVR microcontroller with 48KB flash and 6KB SRAM. It operates from 1.8V to 5.5V at 20MHz. Features include brown-out detection, POR, and WDT. The 32-VFQFN package supports extreme environments up to 125°C.
- Extended temperature range: -40°C to 125°C for automotive and industrial use.
- Large SRAM: 6KB enables complex data buffering.
- High reliability: BOD and WDT prevent system lockups.
- Compact thermal package: Exposed pad improves heat dissipation.
Automotive Engine Control
125°C rating and 48KB flash handle harsh under-hood sensor and actuator management.
Industrial Robotics
6KB SRAM and 20MHz core support real-time kinematics for small robotic arms.
Smart Grid Meters
Wide temperature range and WDT ensure reliable operation in outdoor utility meters.
Aerospace Avionics
High-temperature tolerance and robust POR suit cabin pressure or fuel monitoring systems.
Heavy Machinery
QFN package with exposed pad aids thermal dissipation in vibration-prone excavator controllers.
Data Loggers
Large memory and low-power modes enable long-term environmental data recording.
