The Microchip ATMEGA164PA-AUR is an 8-bit AVR microcontroller with 16KB flash and 1KB SRAM. It runs at 20MHz with a 1.8V to 5.5V supply range. The 44-TQFP package includes PWM, watchdog timer, and brown-out detection, making it a cost-effective choice for simple control and sensing applications.
- Ultra-low voltage: 1.8V operation enables single-cell battery designs.
- Proven AVR core: Extensive toolchain and community support reduce development time.
- Integrated safety: BOD and WDT improve system reliability in noisy environments.
- Compact 44-pin package: Saves PCB space while providing ample I/O.
Battery-Powered Remote Controls
1.8V minimum operation and low-power sleep modes extend battery life in consumer remotes and IoT switches.
Sensor Data Loggers
16KB flash and 1KB SRAM are sufficient for logging temperature or humidity data with timestamps.
Small Appliance Controllers
20MHz speed and PWM outputs control heating elements and motors in coffee makers and air purifiers.
Automotive Aftermarket Modules
5V operation and -40 to 85°C rating suit car alarm sensors and window control modules.
Educational Prototyping
The AVR architecture is well-documented, making it ideal for teaching embedded systems with 44-pin DIP/TQFP boards.
Industrial Relay Logic
Robust WDT and BOD ensure fail-safe operation in PLC-like relay controllers.
