Electrical and Interface Characteristics
Low Voltage, Low Power Consumption: The UC1672C module operates at 3.0V or 5.5V logic levels with low power consumption, making it highly suitable for battery-powered portable devices.
Interface Options: The UC1601S supports multiple interfaces, including SPI or I²C. The I²C interface (requiring only two signal wires) is favoured in practical applications due to its minimal MCU pin resource usage and straightforward wiring.
COG Packaging: The adoption of COG (Chip-On-Glass) packaging is one of its key features. The driver IC is directly bonded onto the LCD glass substrate, resulting in a thinner, lighter module with more reliable connections and improved immunity to interference.
Structure and Mechanical Properties
Wide Temperature Operation: Commercial-grade modules typically support an operating temperature range of -20°C to +70°C. Certain models optimised for industrial environments even support an ultra-wide range of -30°C to +85°C, offering greater adaptability.
Robust Durability: The COG packaging process and mature liquid crystal technology ensure high reliability, enabling adaptation to the vibration and prolonged operation demands of numerous industrial environments.

Performance Specifications:
Wide operating temperature range: This product supports -30°C to +80°C, ensuring stable and reliable operation.
Long service life and high stability.
Display Technology and Performance: The UC1672C drives monochrome segment displays. VA material provides excellent contrast and viewing angles.
Interface Options:
I²C Interface: Requires only two signal lines (SCL, SDA), significantly conserving MCU pin resources. This makes it the preferred choice for projects with limited pin availability, though communication speeds are comparatively lower.
SPI Interface: Offers faster communication speeds than I²C, suitable for scenarios requiring quicker refresh rates.
Power Management and Low Power Consumption: The UC1672C's ultra-low power consumption is one of its core strengths. Its integrated charge pump and voltage regulator enable operation from a single power supply (e.g., 3.3V), eliminating the need for complex external power circuits.
Software-Adjustable Contrast: Display contrast can be adjusted via software commands, eliminating the need for external potentiometers and simplifying hardware design and production debugging.
COG Packaging Advantages: The COG (Chip on Glass) process bonds the driver IC directly onto the LCD glass substrate. This results in a thinner, lighter module with more reliable connections and enhanced resistance to vibration and interference.
Automotive Electronics: Applied to in-vehicle speed and information display units, adapted to temperature variations within the vehicle.
