The Microchip ATMEGA169PA is an 8-bit AVR microcontroller with an integrated LCD controller, 16KB flash, and 1KB SRAM. Operating from 1.8V to 5.5V at 16MHz, it includes brown-out detection, POR, PWM, and WDT. The 64-VQFN package is designed for compact display-based applications.
- Integrated LCD driver – reduces BOM cost and PCB area.
- Wide voltage range (1.8V-5.5V) – flexible power supply options.
- 16KB flash – sufficient for display and control firmware.
- 64-pin VQFN – compact with good thermal performance.
LCD-Based Instrumentation
The integrated LCD driver directly interfaces with segment LCDs, eliminating external driver ICs. The 16MHz AVR core handles display refresh and measurement logic.
Smart Meters
With 1.8V-5.5V operation and low power, it suits utility meters. The 64-pin package allows multiple I/O for communication interfaces.
Portable Medical Displays
The LCD controller and low power enable handheld glucose meters or thermometers. The -40°C to 85°C range covers clinical environments.
Industrial Panel Meters
PWM outputs and WDT ensure reliable operation in process control. The exposed pad aids thermal dissipation in sealed enclosures.
Consumer Appliances with Displays
Washing machines or microwaves can use the LCD driver for user interface. The 16KB flash stores multiple language strings.
