The ATMEGA64L-8MU is a low-power 8-bit AVR microcontroller from Microchip, designed for voltage-flexible applications. It operates from 2.7V to 5.5V at 8MHz, featuring 64KB flash and 4KB SRAM in a 64-VFQFN package. With integrated PWM, WDT, and brown-out detection, it balances performance and energy efficiency for portable and industrial designs.
- Wide voltage range (2.7V-5.5V): Enables direct battery operation and compatibility with 3.3V or 5V logic.
- Low-power 8MHz operation: Reduces current consumption, ideal for energy-harvesting and battery devices.
- 64KB flash: Supports complex firmware with OTA update capability.
- Compact VFQFN-64: Saves PCB space while providing exposed pad for thermal management.
Battery-Powered Sensor Nodes
The 2.7V minimum supply and 8MHz clock allow energy-efficient operation in wireless sensor networks, extending battery life while maintaining 64KB flash for data logging.
Portable Medical Instruments
Low-voltage operation (2.7V-3.3V) suits handheld glucose meters and pulse oximeters, with WDT ensuring fail-safe operation during patient monitoring.
Consumer Electronics Remote Controls
The 8MHz AVR core with 4KB SRAM handles IR protocol encoding, while low-power sleep modes preserve battery in TV remotes and smart home controllers.
Environmental Monitoring Loggers
With 64KB flash, it stores months of temperature/humidity data, and the 2.7V-5.5V range accommodates solar or battery power in remote stations.
Wearable Fitness Trackers
The compact VFQFN package and low-voltage operation enable slim designs, with PWM driving haptic feedback and LED indicators.
Automotive Interior Lighting
Operates from 3.3V or 5V rails, controlling LED dimming via PWM, while brown-out detection prevents erratic behavior during cranking.
