The ATMEGA644P-A15AZ from Microchip Technology is a high-performance 8-bit AVR microcontroller. It combines 64KB Flash, 4KB SRAM, and a rich peripheral set including PWM, WDT, and brown-out detection. Operating from 2.7V to 5.5V at up to 16MHz, it delivers reliable performance in a compact 44-TQFP package for demanding industrial and automotive environments.
- Wide voltage range (2.7V-5.5V) simplifies power supply design and supports battery operation.
- High-temperature rating (-40°C to 125°C) ensures reliability in harsh environments.
- 64KB Flash provides ample code space for complex applications.
- Integrated brown-out detect and watchdog enhance system robustness.
Industrial Automation
With a wide 2.7V-5.5V supply range and 16MHz AVR core, it handles sensor interfacing and motor control in PLCs and industrial controllers.
Automotive Body Electronics
Rated for -40°C to 125°C, it suits under-hood modules like window lifters and lighting control, with PWM for actuator drive.
Smart Sensors
4KB SRAM and 64KB Flash enable local data logging and edge processing for temperature, pressure, and flow sensors.
Power Management
Brown-out detection and watchdog timer ensure reliable operation in power supplies and battery chargers.
Consumer Appliances
Low-power modes and robust I/O make it ideal for washing machines, microwaves, and smart home hubs.
Medical Monitoring
High-temperature tolerance and deterministic AVR core support portable diagnostic devices and patient monitors.
