PCF2119RU/2DB/2Z

Display Drivers Overview

The PCF2119RU/2DB/2Z is a low-power CMOS LCD controller and driver designed for dot matrix displays. It supports 2-line by 16-character or 1-line by 32-character formats with 5x8 dot characters. The device features an on-chip configurable voltage multiplier (4x, 3x, or 2x) generating LCD bias voltages independent of VDD. It includes a Character Generator ROM (CGROM) for 240 characters and RAM (CGRAM) for 16 user-defined symbols. Interfaces include a 4-bit or 8-bit parallel bus and a 2-wire I²C-bus.

Display Drivers Feature Summary

• Single-chip integration providing full LCD control and driving capabilities with reduced external component requirements.
• Supports icon blink functions and multiple display modes including alphanumeric and kana character sets.
• On-chip temperature compensation for generated LCD supply voltage to ensure stable operation across operating ranges.
• Flexible connectivity via standard parallel bus or low-pin-count I²C interface compatible with most microcontrollers.

Display Drivers Applications

• Dot matrix LCD displays requiring 2 lines of 16 characters
• Dot matrix LCD displays requiring 1 line of 32 characters
• Systems utilizing icon-based interfaces with blink functionality

Display Drivers Procurement Notes

Verify the specific suffix 'RU/2DB/2Z' against official NXP documentation to confirm exact binning, tape-and-reel specifications, and environmental compliance status. Ensure the ordering code matches the required package variant and character set configuration before procurement.

Display Drivers Selection Notes

Select this component when a single-chip solution is needed for dot matrix LCDs with minimal external circuitry. It is suitable for designs requiring both parallel and I²C interface flexibility. Consider the on-chip voltage generation if external bias circuits are undesirable. Verify that the required character set and icon definitions align with the built-in CGROM and available CGRAM resources.

Display Drivers Part Context

This part belongs to the PCF2119x series of LCD controllers from NXP Semiconductors. The series is characterized by its low power consumption and high integration level, designed specifically for driving character-based dot matrix displays in embedded applications.

Display Drivers Replacement Considerations

Consult official NXP substitution lists for form-fit-function compatible alternatives. Generic LCD controllers may not support the specific I²C protocol or on-chip voltage generation features without hardware modifications.
