The Microchip ATMEGA3290-16AUR is a high-performance 8-bit AVR microcontroller in a 100-TQFP package. It combines 32KB of flash memory, 2KB SRAM, and a rich peripheral set including an LCD controller, PWM, and watchdog timer. Operating from 2.7V to 5.5V at up to 16MHz, it is engineered for demanding embedded control applications.
- Integrated LCD Driver: Reduces external components and BOM cost for display applications.
- Wide Voltage Range (2.7V-5.5V): Simplifies power supply design and supports battery operation.
- High Integration: Includes POR, BOD, and WDT for enhanced system reliability.
- 100-Pin TQFP: Offers ample I/O for complex interfacing needs.
Industrial Control Panels
With a 16MHz AVR core and 32KB flash, it handles real-time control loops and HMI updates via its integrated LCD driver.
Portable Medical Monitors
The 2.7V-5.5V supply and low-power modes enable battery-operated devices, while the LCD port displays vital signs directly.
Smart Energy Meters
Its PWM outputs and analog comparators support accurate measurement and control for utility metering applications.
Automotive Aftermarket Displays
The wide temperature range (-40°C to 85°C) and robust I/O make it reliable for dashboard or climate control modules.
Home Appliance User Interfaces
Integrated LCD and capacitive touch sensing (via external circuitry) allow for sleek, responsive control panels.
Data Logging Systems
2KB SRAM and 32KB program memory provide sufficient buffer for sensor data logging with periodic EEPROM writes.
