Introduction
As wearable and portable devices continue to shrink in size, the demand for small, high-performance displays has never been greater. The SFOS049XZ-7111AN from Saef Technology Limited is a 0.49-inch OLED module that delivers crisp monochrome visuals, low power consumption, and a simple I2C interface—making it an ideal choice for space-constrained applications.

Optical Performance: Bright and Clear
With a typical brightness of 180 cd/m² and a high contrast ratio of 2000:1, this OLED module ensures excellent readability even in brightly lit environments. Its self-emissive nature allows for a wide viewing angle and fast response times, making it suitable for dynamic content such as notifications, sensors readouts, and status indicators.
Power Efficiency and Flexibility
The module supports two power configurations:
In sleep mode, the display consumes as little as 1µA (VDD) and 2µA (VCC), making it ideal for battery-powered devices. The inclusion of an internal charge pump reduces external component count and simplifies design.
I2C Interface: Easy Integration
The I2C interface supports clock speeds up to 3.3MHz and requires only two signal lines (SCL, SDA). This simplifies integration with popular microcontrollers such as those from STM32, ESP32, and nRF series. The module also includes a reset pin (RES#) and brightness control via the IREF pin.
Built for Reliability
The SFOS049XZ-7111AN has been tested under stringent conditions, including:
-
High-temperature operation (70°C for 240 hours)
-
Low-temperature storage (-40°C for 240 hours)
-
Thermal shock cycling (-40°C ↔ 85°C)
These tests ensure stable performance in medical, industrial, and consumer applications.
Conclusion
The SFOS049XZ-7111AN combines compact size, high optical performance, and low power consumption in a robust package. Whether you're designing a smart wearable, a handheld instrument, or an IoT device, this OLED module offers the clarity and reliability you need.
