The ATMEGA3290PA-AU is an 8-bit AVR microcontroller with a built-in LCD driver, packaged in a 100-pin TQFP. It operates at up to 20MHz with a supply voltage of 2.7V to 5.5V, offering 32KB of flash and 2KB of RAM. Features include brown-out detection, POR, PWM, and WDT for robust display-based applications.
- Integrated LCD: reduces external components and PCB space.
- High speed: 20MHz enables fast UI response and complex calculations.
- Large I/O: 100-pin package supports extensive peripheral connectivity.
- Low power: suitable for battery-operated devices with sleep modes.
Smart Meters
Integrated LCD driver and 20MHz speed enable real-time energy usage display.
Industrial HMI Panels
100-pin TQFP provides ample I/O for keypads and LED indicators alongside LCD.
Medical Devices
2KB RAM supports waveform buffers for portable ECG or spirometer displays.
Automotive Clusters
Wide voltage range (2.7-5.5V) and -40°C to 85°C rating suit dashboard environments.
Home Automation Gateways
PWM outputs control dimmers, while LCD shows status of multiple zones.
Portable Instrumentation
Low-power sleep modes and LCD driver extend battery life in handheld multimeters.
