Description and Introduction

LCD column driver for dot matrix graphic displays The **PCF8579T** is a versatile peripheral interface IC designed to simplify the integration of LCD displays in embedded systems. As an I²C-compatible LCD driver, it efficiently manages up to 40 segments, making it ideal for applications requiring compact, low-power alphanumeric or symbolic displays.  

Featuring a built-in oscillator and requiring minimal external components, the PCF8579T reduces design complexity while ensuring reliable performance. Its I²C serial interface allows seamless communication with microcontrollers, minimizing wiring and freeing up GPIO pins for other functions. The device supports both static and multiplexed LCD driving modes, offering flexibility for various display configurations.  

Key advantages include low power consumption, making it suitable for battery-operated devices, and a wide operating voltage range (2.5V to 6V), ensuring compatibility with diverse systems. Additionally, its auto-increment addressing simplifies software control, streamlining development.  

Common applications include industrial control panels, consumer electronics, and instrumentation where clear, low-power display solutions are essential. By combining ease of use with robust functionality, the PCF8579T serves as a practical solution for designers seeking efficient LCD interfacing in space-constrained environments.  

For detailed specifications, consult the official datasheet to ensure proper implementation in your design.

Application Scenarios & Design Considerations

LCD column driver for dot matrix graphic displays

Alternative Part Number

  • PCF8578T --: Same PCF857x LCD driver family with similar I2C interface and drive capability, but a different variant number so it is clearly distinguishable from the source part.
  • PCF8576DT --: NXP LCD segment driver from the same PCF857x family with comparable I2C control and display driving features, suitable as a functional substitute in many designs.
  • PCF8566T --: NXP LCD driver IC with similar I2C interface and segment driving function, offering a practical cross-reference when the exact PCF8579T is unavailable.
  • PCF8578T --: Same PCF857x LCD driver family from the original Philips spin-off NXP, with a closely matching I2C LCD dot-matrix driver function and similar package options.
  • HD44100H --: Common LCD segment/dot-matrix column driver IC widely used alongside LCD controllers, offering a comparable display-driving role for LCD module designs.
  • PCF8576DT --: NXP I2C LCD driver in the same PCF857x family, suitable as a functional substitute when the exact dot-matrix driver configuration is not critical.
  • PCF8578T --: Same PCF857x LCD driver family from NXP (formerly Philips); similar I2C LCD segment driver function and package, often used as a close substitute when the exact variant is unavailable.
  • PCF8576DT --: NXP I2C LCD segment driver in the same PCF857x family with comparable interface and supply requirements; a practical alternative for many LCD driver applications.
  • PCF8566T --: NXP I2C LCD driver in the same legacy Philips LCD driver portfolio, offering similar I2C control and display driving capability for replacement consideration.
