The ATMEGA3290A-AU from Microchip Technology is a high-performance 8-bit AVR microcontroller in a 100-TQFP package. It operates at up to 20MHz with a supply voltage range of 1.8V to 5.5V. Featuring 32KB of in-system programmable flash, 2KB SRAM, and an integrated LCD controller, it is designed for applications requiring direct display driving and complex control logic. Its industrial temperature range and robust peripheral set make it a versatile choice for embedded systems.
- Integrated LCD Driver: Eliminates the need for external display driver ICs, reducing BOM cost and board space.
- Wide Voltage Range (1.8V-5.5V): Supports both 3.3V and 5V systems, simplifying power supply design.
- High Throughput at 20MHz: Executes most instructions in a single clock cycle, delivering up to 20 MIPS for responsive control.
- Robust Protection Features: Includes brown-out detection and watchdog timer for reliable operation in noisy environments.
Industrial Control Panels
With an integrated LCD driver and 20MHz AVR core, the ATMEGA3290A-AU can directly drive alphanumeric displays in industrial HMI panels, reducing external component count.
Medical Monitoring Devices
The wide 1.8V-5.5V supply range and low-power sleep modes make it suitable for battery-operated patient monitors requiring reliable data logging.
Smart Meters
Its 32KB flash and 2KB SRAM handle complex metering algorithms while the LCD interface displays consumption data in real time.
Automotive Aftermarket Clusters
Operating from -40°C to 85°C, it can replace mechanical gauges with a cost-effective digital LCD cluster.
