The Microchip ATMEGA324A-CUR is an 8-bit AVR microcontroller with 32KB flash and 2KB SRAM, running at up to 20MHz. It operates from 1.8V to 5.5V, featuring brown-out detection, POR, PWM, and a watchdog timer. Packaged in a compact 49-VFBGA, it suits space-limited, low-power embedded systems requiring robust performance.
- Ultra-wide voltage range (1.8-5.5V): Simplifies dual-voltage designs and supports both 3.3V and 5V logic.
- High integration in VFBGA: Saves PCB area for wearables and compact IoT modules.
- 20MHz AVR core: Executes most instructions in one clock cycle, maximizing throughput per MHz.
- Robust reset features: Brown-out and POR prevent data corruption during power glitches.
IoT Edge Nodes
The 1.8V operation and 2KB SRAM support low-power MQTT/CoAP clients in smart home sensors, collecting data from analog peripherals.
Industrial Control Panels
With 32KB flash and 20MHz speed, it manages HMI keypads, LED indicators, and Modbus RTU communication in factory automation.
Medical Monitoring Devices
Reliable POR and brown-out detection ensure safe operation in glucose meters and pulse oximeters, with 5V tolerance for analog front-ends.
Automotive Body Electronics
Operating from -40°C to 85°C, it handles window lift controllers and seat position memory, using PWM for motor speed regulation.
Portable Instrumentation
The VFBGA package reduces footprint in handheld multimeters and data loggers, while 5.5V max supply allows direct battery connection.
Smart Agriculture
Used in soil moisture probes and weather stations, leveraging the watchdog timer for unattended field operation.
