PCF2119AU/2DA/2,02

Display Drivers Overview

The PCF2119AU/2DA/2,026 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 configurations using 5x8 dot formats. The device integrates on-chip LCD bias voltage generation, reducing external component requirements. It interfaces with microcontrollers via a 4-bit or 8-bit parallel bus or a 2-wire I²C-bus. Key internal resources include 80 characters of Display Data RAM (DDRAM), 240 characters of Character Generator ROM (CGROM), and 16 characters of Character Generator RAM (CGRAM).

Display Drivers Feature Summary

• Single-chip integration providing full LCD control and driving capabilities.
• Built-in configurable voltage multiplier generating LCD supply voltages independent of VDD.
• Supports icon blink functions and multiple display modes including alphanumeric and kana characters.
• On-chip oscillator requires no external components for clock generation.

Display Drivers Applications

• Driving 2-line by 16-character dot matrix LCD modules.
• Driving 1-line by 32-character dot matrix LCD modules.
• Embedded systems requiring alphanumeric display with icon support.

Display Drivers Procurement Notes

Verify the specific suffix '2,026' against official NXP documentation to confirm package type and availability status. As this part number may be discontinued or subject to change, consult the manufacturer's current product longevity program data. Ensure that the required character set and interface configuration match the design specifications before procurement.

Display Drivers Selection Notes

Select this component when a single-chip solution for dot matrix LCDs is required with minimal external circuitry. It is suitable for applications needing I²C or parallel bus connectivity. Consider the available CGROM and CGRAM capacities for character customization needs. Verify power supply constraints as the device operates within a specific voltage range.

Display Drivers Part Context

The PCF2119x series represents NXP's low-power CMOS LCD controllers. This family is engineered for cost-effective and space-constrained embedded displays. The 'x' denotes variations in built-in character sets. These devices are commonly used in industrial, consumer, and automotive instrumentation where reliable alphanumeric output is essential.

Display Drivers Replacement Considerations

Check NXP's official substitution list for form-fit-function compatible alternatives. Verify if newer generations offer enhanced features or improved longevity. Ensure any replacement maintains compatibility with the existing I²C or parallel bus protocol and pinout configuration.
