The Microchip ATMEGA164P-20MQ is an 8-bit AVR MCU running at 20MHz. It includes 16KB flash and 1KB RAM in a 44-VFQFN package. Operating from 2.7V to 5.5V, it features PWM, WDT, and Brown-out Reset. With a -40°C to 105°C range, it is built for industrial and automotive environments.
- Wide voltage range (2.7V-5.5V): Direct battery operation without regulators.
- 20MHz AVR core: Fast execution for 8-bit applications.
- Exposed pad package: Improved thermal performance for high-power designs.
- 105°C operating temperature: Suitable for under-hood and industrial settings.
- Integrated PWM and WDT: Reduces external components.
Automotive Body Electronics
With 105°C rating and 5.5V operation, it handles door modules and lighting control directly from vehicle battery.
Industrial Sensor Nodes
The 20MHz AVR core processes analog signals quickly. The exposed pad aids thermal dissipation in sealed enclosures.
Consumer Robotics
Use PWM for servo control and WDT for safety. The 16KB flash supports basic autonomous behaviors.
Smart Agriculture Sensors
Operate on battery with 2.7V minimum. The low-power sleep modes extend field deployment time.
HVAC Controllers
Handle temperature sensing and fan speed control. The robust I/O tolerates noisy industrial power lines.
Portable Instrumentation
Combine 5V operation with low power for handheld meters. The compact QFN package reduces PCB size.
