The ATMEGA8A-AN from Microchip is a high-performance 8-bit AVR microcontroller with 8KB of in-system programmable flash. It operates from 2.7V to 5.5V at speeds up to 16MHz. The device includes 1KB SRAM, PWM channels, and a watchdog timer, all housed in a 32-TQFP package. Its extended temperature range up to 105°C makes it suitable for demanding industrial and automotive environments.
- High noise immunity: The AVR core is designed for reliable operation in electrically noisy environments.
- Wide temperature range: -40°C to 105°C supports harsh industrial applications.
- Integrated PWM: Reduces external components for motor and lighting control.
- 5V compatible: Simplifies interfacing with legacy 5V logic and sensors.
Motor Control for Drones
The integrated PWM and 16MHz AVR core allow precise speed control of brushless DC motors in small quadcopters.
Automotive Aftermarket Sensors
With an operating range up to 105°C, it can handle under-hood temperature sensors or oil pressure monitors.
Industrial Relay Logic
Its 5V operation and robust I/O make it a drop-in replacement for older 8051-based relay controllers in legacy equipment.
Consumer Appliances
Washing machine control boards benefit from the 8KB flash for wash cycle programs and the WDT for fault recovery.
Educational Robotics Kits
The simple AVR instruction set and 32-TQFP package are ideal for hobbyist robot controllers with multiple servo outputs.
Power Supply Monitoring
Brown-out detection ensures safe shutdown of SMPS controllers when input voltage drops below 2.7V.
