PCF2119DU/2/2Z

Display Drivers Overview

The PCF2119DU/2/2Z is a low-power CMOS single-chip LCD controller and driver manufactured by NXP. It is designed to drive dot matrix LCD displays, supporting configurations of up to 2 lines by 16 characters or 1 line by 32 characters using a 5x8 dot format. The device integrates essential display functions, including on-chip generation of LCD bias voltages, which minimizes external component requirements and reduces system current consumption. It interfaces with microcontrollers via a 4-bit or 8-bit parallel bus or a 2-wire I²C-bus.

Display Drivers Feature Summary

• Integrates character generator ROM for alphanumeric and kana characters alongside user-defined symbol capabilities
• Features on-chip configurable voltage multiplier and temperature compensation for stable LCD operation
• Supports icon blink functionality and reduced current consumption modes for power efficiency

Display Drivers Applications

• Dot matrix LCD display driving in embedded systems
• Industrial control panels requiring alphanumeric output
• Consumer electronics with simple graphical user interfaces

Display Drivers Procurement Notes

Verify the specific suffix 'DU/2/2Z' against official NXP documentation to confirm package type and tape/reel specifications. Confirm availability status as the PCF2119x series may be subject to end-of-life notices. Ensure compatibility with existing PCB footprints and interface voltage levels before procurement.

Display Drivers Selection Notes

Select this component when a low-pin-count solution for small dot matrix displays is required. It is suitable for applications needing integrated bias generation and multiple interface options (parallel or I²C). Consider the character set requirements, as the base model supports standard alphanumeric and kana sets with optional user-defined symbols.

Display Drivers Part Context

The PCF2119x series belongs to NXP's portfolio of single-chip LCD controllers. These devices are engineered for cost-effective and space-constrained applications. The series provides a complete solution for driving character-based LCDs without requiring external voltage regulators or complex driver circuits, simplifying system design.

Display Drivers Replacement Considerations

Consult NXP's official product change notification and longevity documents for form-fit-function compatible alternatives. Verify if newer revisions of the PCF2119x series are available. Cross-reference pinouts and electrical characteristics with potential substitutes to ensure seamless integration.
