The Microchip ATMEGA165PV-8AUR is an 8-bit AVR microcontroller in a 64-TQFP package. It operates from 1.8V to 5.5V at speeds up to 8MHz, with 16KB flash and 1KB SRAM. Integrated peripherals include brown-out detection, POR, PWM, and WDT, making it a robust choice for low-power embedded control.
- Ultra-low voltage operation (1.8V) – enables direct battery power without boost converters, reducing BOM cost.
- Integrated brown-out detect/reset – prevents system corruption during voltage sags, improving reliability.
- Compact 64-TQFP package – saves PCB space while providing up to 54 I/O pins for complex interfaces.
- Wide temperature range (-40°C to 85°C) – suitable for outdoor and industrial environments.
Battery-Powered Sensor Nodes
The 1.8V minimum supply voltage allows direct operation from two AA batteries or a Li-ion cell, while the 8MHz clock reduces dynamic power consumption, extending battery life in remote monitoring systems.
Industrial Control Panels
With a 64-TQFP package and 16KB flash, it can handle multiple I/O lines for switch inputs, LED indicators, and relay control, while the WDT ensures reliable operation in noisy industrial environments.
Portable Medical Devices
The low-voltage operation and small footprint make it suitable for handheld glucose meters or pulse oximeters, where the 1KB SRAM supports real-time data buffering and the PWM can drive haptic feedback motors.
Smart Home Thermostats
Its 5.5V maximum supply allows direct connection to 5V-regulated rails, while the brown-out detect/reset prevents erratic behavior during power dips, ensuring consistent temperature control.
Automotive Aftermarket Accessories
Operating from -40°C to 85°C, it can be used in car alarm systems or window controllers, where the POR circuit ensures clean startup from the vehicle's 12V-to-5V converter.
HVAC Zone Controllers
The 16KB program memory is sufficient for PID control algorithms, and the PWM outputs can directly drive triac-based heater actuators, while the WDT monitors for software hangs.
