Universal LCD driver improves display capabilities

26-04-2024 | WIN SOURCE | Industrial

The NXP Semiconductors universal LCD driver PCF8576DT/F2,518 component, available from WIN SOURCE, is a powerful solution for connecting virtually any LCD with low multiplex rates, supplying unparalleled versatility across many applications.

At its core, the design features a single-chip LCD controller and driver functionality, supporting various backplane drive configurations, including static or up to four backplane multiplexing. It offers selectable display bias configurations of static, 1/2, or 1/3 bias, and enhances configurations with internal LCD bias generation through voltage follower buffers. Capable of driving up to 40 segment outputs, it accommodates up to 20 seven-segment numeric characters, up to ten 14-segment alphanumeric characters, or any graphics comprising up to 160 segments/elements.

Equipped with a 40×4-bit RAM for efficient display data storage, the component facilitates automatic incrementing of display data loading across device subaddress boundaries and offers versatile blinking modes. It contributes to providing separate supplies for LCD and logic voltages, with a comprehensive power supply range from 1.8V to 5.5V, and logic LCD supply ranging from 2.5V for low-threshold LCDs to 6.5V for high-threshold twisted nematic LCDs.

This universal LCD driver stands out for its low power consumption and robust 400kHz I2C-bus interface, making it an excellent choice for energy-sensitive applications demanding high-performance display solutions. Designed for scalability, it can be cascaded for large LCD applications up to 2560 segments/elements without needing external components, compatible with chip-on-glass and chip-on-board technology, and manufactured using a silicon gate CMOS process for enhanced reliability and performance.

The driver is suited to various applications, including handheld wireless systems, industrial controls, automotive dashboards, and other systems needing flexible, low-power LCD display solutions, meeting the AEC-Q100 standard for automotive applications, underscoring its reliability in challenging conditions.

The introduction of the PCF8576DT/F2,518 marks a notable advancement in integrating precision LCD displays into electronic projects, supplying enhanced user interfaces and functionalities for various devices.
