The Microchip ATMEGA169A-MUR is an 8-bit AVR microcontroller in a compact 64-VFQFN package. It operates from 1.8V to 5.5V at up to 16MHz, featuring 16KB flash, 1KB SRAM, and an integrated LCD controller. On-chip peripherals include PWM, watchdog timer, brown-out reset, and power-on reset, making it a self-contained solution for display-centric embedded designs.
- Integrated LCD controller: Directly drives segment displays without external ICs, reducing BOM cost.
- Wide 1.8V-5.5V supply: Flexible for battery or regulated 3.3V/5V systems.
- Low-power AVR core: Efficient sleep modes extend battery life in portable devices.
- Robust reset features: Brown-out and power-on reset ensure reliable startup in noisy environments.
Battery-Powered LCD Meters
The 1.8V minimum supply and integrated LCD driver allow direct display readouts in portable multimeters and utility meters, reducing external components.
Industrial Control Panels
With PWM, WDT, and brown-out detection, it can manage motor speed control and status displays in harsh environments, operating reliably from -40°C to 85°C.
Home Automation Thermostats
Its low-power sleep modes and LCD interface make it ideal for wall-mounted thermostats that need continuous time/temperature display with minimal energy draw.
Medical Monitoring Devices
The 16KB flash and 1KB SRAM support simple sensor data logging and waveform display on small LCD screens, while the POR ensures safe startup.
Automotive Aftermarket Gauges
Although not AEC-Q100, its wide voltage range and robust reset circuitry suit 12V vehicle systems with proper regulation, driving custom segment displays.
Portable Data Loggers
Combine the AVR core's efficient instruction set with WDT for field data capture, storing readings in external EEPROM and showing status on the built-in LCD.
