The ATMEGA324A-CU is a high-performance 8-bit AVR MCU in a space-saving 49-VFBGA. It runs at up to 20MHz with 32KB flash and 2K SRAM. Operating from 1.8V to 5.5V, it integrates PWM, WDT, POR, and brown-out detection for reliable embedded control.
- 20MHz AVR core – fast execution for real-time control loops.
- 1.8V low-voltage operation – extends battery life in portable designs.
- 49-VFBGA – ultra-compact footprint for space-constrained PCBs.
- Rich peripheral set (PWM, WDT, POR) – reduces external IC count.
Portable Medical Devices
1.8V operation and 20MHz speed enable glucose meters and pulse oximeters with fast ADC sampling.
Industrial Automation Sensors
32KB flash and 2K RAM handle calibration tables and Modbus protocol stacks in proximity sensors.
Smart Home Hubs
VFBGA package saves PCB space for compact Zigbee or Thread border routers.
Automotive Body Electronics
Wide voltage range and -40°C to 85°C support window lift controllers and mirror modules.
Robotics Controllers
PWM channels drive hobby servos while AVR core runs inverse kinematics at 20MHz.
Data Loggers
Low-power sleep modes and 2K SRAM buffer sensor readings before writing to external EEPROM.
