The Microchip ATMEGA164A-MUR is a high-performance 8-bit AVR microcontroller in a compact 44-VFQFN package. It operates from 1.8V to 5.5V at speeds up to 20MHz, with 16KB of flash memory and 1KB of SRAM. Integrated features include Brown-out Detect/Reset, Power-on Reset, PWM channels, and a Watchdog Timer, ensuring reliable operation in demanding environments. Its wide temperature range (-40°C to 85°C) and low-power capabilities make it ideal for industrial, automotive, and portable applications.
- Wide Voltage Flexibility: 1.8V-5.5V operation supports both 3.3V and 5V logic without external level shifters.
- Compact Thermal Package: 44-VFQFN with exposed pad improves heat dissipation in space-constrained designs.
- Reliable Reset Management: Integrated Brown-out Detect and POR prevent erratic behavior during power fluctuations.
- Low-Power Operation: Multiple sleep modes extend battery life in portable sensor applications.
Industrial Sensor Nodes
With a 1.8V minimum supply and low-power sleep modes, the ATMEGA164A-MUR excels in remote industrial sensors that must run for years on coin cells or energy harvesters.
Motor Control for Small Appliances
The 20MHz AVR core with hardware PWM and WDT enables precise, reliable commutation for brushless DC motors in fans, pumps, and kitchen appliances.
Portable Medical Monitors
Its 5.5V maximum input tolerance simplifies direct battery connection, while the 16KB flash and 1KB SRAM handle real-time vital-sign algorithms.
Automotive Body Electronics (Non-Safety)
The -40°C to 85°C range and robust Brown-out Reset make it suitable for interior lighting control, window lift modules, and seat adjustment units.
Smart Home Thermostats
Combining PWM for heater control, WDT for fail-safe operation, and low-voltage operation, it provides a cost-effective brain for HVAC zone controllers.
Battery Management Systems (BMS) for 2S Packs
The 1.8V operation allows direct monitoring of cell voltages without level shifters, while the 44-VFQFN package saves space in compact BMS PCBs.
