The Microchip ATMEGA325PV-10MUR is an 8-bit AVR microcontroller in a compact 64-VFQFN package. It operates from 1.8V to 5.5V and runs at up to 10MHz, delivering efficient processing for power-conscious designs. With 32KB of flash memory and 2KB of SRAM, it provides ample space for firmware and data. Integrated peripherals include PWM, brown-out detection, power-on reset, and a watchdog timer, ensuring reliable operation in demanding environments. Its wide temperature range and low-power capabilities make it a versatile choice for industrial and portable applications.
- Ultra-low power consumption: The 1.8V operation and multiple sleep modes extend battery life in portable devices.
- Wide voltage flexibility: Accepts 1.8V to 5.5V, simplifying power supply design and supporting both 3.3V and 5V systems.
- Robust reset management: Integrated brown-out detection and power-on reset prevent erratic behavior during power fluctuations.
- Compact 64-VFQFN package: Saves PCB space while providing excellent thermal performance for enclosed designs.
Battery-Powered Sensor Nodes
The 1.8V minimum supply voltage and multiple sleep modes enable long battery life in wireless sensor networks, where the 10MHz clock is sufficient for periodic data acquisition and transmission.
Industrial Control Panels
With a 5.5V maximum supply and robust I/O, this MCU can interface directly with industrial logic levels, while the PWM channels drive actuators and the WDT ensures fail-safe operation in noisy environments.
Portable Medical Devices
The low-power AVR core and 2KB SRAM support real-time processing of biosignals, and the -40°C to 85°C range covers clinical and home-use environments.
Automotive Aftermarket Modules
Its wide voltage tolerance handles unregulated vehicle power, and the brown-out detector resets the system safely during cranking voltage dips, protecting calibration data in flash.
Smart Metering Infrastructure
The 32KB flash stores calibration and logging data, while the UART/SPI interfaces communicate with metering ICs; the low-power mode extends battery life in remote utility meters.
HVAC Zone Controllers
PWM outputs directly drive fan speed controllers, and the 10MHz core handles PID loops at adequate rates, while the exposed pad package aids thermal dissipation in enclosed thermostat housings.
