- Extended Temperature Range: Rated for -40°C to 105°C, suitable for industrial and automotive environments.
- High I/O Count: The 44-pin package provides up to 32 I/O lines for complex interfacing.
- Mature AVR Ecosystem: Extensive documentation, libraries, and tools reduce development time.
Industrial Automation I/O
The 44-VFQFN package provides many I/O pins for reading switches and driving relays. The 105°C rating allows for use in hot control cabinets.
Sensor Networks
With 2KB RAM and multiple UART/SPI interfaces, it can aggregate data from several sensors and transmit via RS-485 or wireless modules.
Battery Management Systems
The 1.8V minimum supply allows for deep discharge operation. The ADC can monitor cell voltages, and the WDT ensures safe operation.
Motor Control (Simple)
The 20MHz AVR core and PWM channels can control DC motors or small steppers with precise speed and direction.
HVAC Controllers
The wide voltage range and robust I/O make it suitable for thermostat and fan coil unit controllers. The 32KB flash supports complex scheduling logic.
Test and Measurement Equipment
The 10-bit ADC and analog comparator enable simple measurement functions. The 105°C rating is beneficial for benchtop equipment in labs.
