The ATMEGA644V-10AU from Atmel is a low-power 8-bit AVR microcontroller. It operates from 1.8V to 5.5V at speeds up to 10MHz, with 64KB flash and 4KB RAM. Its brown-out detection and PWM features enhance reliability in battery-powered and industrial designs. The 44-TQFP package offers a compact footprint.
- Ultra-low voltage operation (1.8V): Enables direct battery operation with minimal power loss.
- 64KB flash memory: Ample space for complex applications and bootloaders.
- Brown-out detection: Prevents data corruption during voltage dips.
- 10MHz AVR core: Balanced performance for mid-range embedded tasks.
Portable Instrumentation
Low-voltage operation down to 1.8V extends battery life in handheld multimeters and data loggers.
Embedded Networking
With 64KB flash, it supports TCP/IP stacks for Ethernet and Zigbee gateway nodes.
Industrial Process Control
Robust brown-out detection and WDT ensure reliable operation in PLC I/O modules.
Consumer Robotics
PWM channels drive servo motors in hobby robots, while 10MHz speed handles sensor fusion.
Agricultural Sensors
Wide temperature range and low power make it suitable for soil moisture and weather stations.
Medical Wearables
1.8V operation and small 44-TQFP package enable compact health monitoring patches.
