The Microchip ATMEGA164PA-CUR is a high-performance 8-bit AVR microcontroller in a space-saving 49-VFBGA package. It delivers 20MHz processing speed with 16KB flash and 1KB SRAM, operating from 1.8V to 5.5V. Built-in Brown-out Detect, POR, PWM, and WDT ensure robust operation across -40°C to 85°C, making it ideal for industrial and portable applications.
- Wide voltage flexibility: 1.8V-5.5V range supports both battery and regulated supplies without external level shifters.
- Compact 49-VFBGA: Reduces PCB area by up to 60% compared to DIP packages, enabling miniaturized designs.
- Integrated safety peripherals: BOD and WDT prevent data corruption and system lockups in noisy environments.
- High-speed AVR core: 20MHz throughput executes most instructions in a single cycle, maximizing real-time response.
Industrial Sensor Nodes
With a 1.8V minimum supply and low-power AVR core, the ATMEGA164PA-CUR excels in battery-powered industrial sensors, enabling long deployment life while monitoring temperature or pressure.
Motor Control for Small Appliances
The integrated PWM channels and 20MHz speed allow precise pulse-width modulation for driving small DC or brushless motors in consumer appliances, with the WDT ensuring fail-safe operation.
Portable Medical Devices
Its 5.5V maximum supply and robust Brown-out Detect make it reliable for handheld glucose meters or pulse oximeters, where consistent voltage monitoring is critical for patient safety.
Automotive Aftermarket Accessories
Operating from -40°C to 85°C, this MCU handles under-hood or cabin electronics like window controllers or seat memory modules, using the 16KB flash for calibration data.
Smart Home Thermostats
The 49-VFBGA package fits into slim thermostat PCBs, while the 1KB SRAM supports simple user interfaces and the POR ensures clean startup on power restoration.
Data Logging Systems
With 16KB program memory and low leakage, it can log environmental data to external EEPROM, using the WDT to recover from software hangs in remote logging stations.
