NXP PCF2119SU LCD Controller/Driver

The NXP PCF2119SU is a versatile LCD controller and driver designed to offer a high-level interface between a microcontroller and an alphanumeric dot matrix liquid crystal display (LCD). This integrated circuit (IC) is ideal for applications that require clear and reliable visual feedback, such as industrial controls, consumer electronics, and handheld instruments.

The PCF2119SU supports a wide range of display configurations, featuring support for up to four lines of characters with each line containing up to 40 characters. Additionally, it provides a rich set of functionalities including multiple character fonts, on-chip generation of the required LCD supply voltage, and a variety of interface options that make it compatible with most microcontrollers.

One of the standout features of the PCF2119SU is its built-in character generator ROM and RAM, which includes a set of predefined characters and allows for the creation of custom characters. This flexibility enables users to display not only alphanumeric data but also custom symbols and graphics that are essential for user-friendly interfaces.

The IC operates on a low power supply, making it an excellent choice for battery-powered devices. Its low power consumption does not compromise performance, ensuring clear visibility and readability under various lighting conditions. Moreover, the PCF2119SU is equipped with an internal voltage multiplier and regulator to manage the LCD driving voltage, which simplifies the design of the power supply circuitry.

For communication with the host microcontroller, the PCF2119SU offers an I²C-bus interface, a 4-bit or 8-bit parallel interface, and an SPI interface. This selection of interfaces ensures that the device can be easily integrated into a wide array of systems without the need for complex wiring or additional components.

In summary, the NXP PCF2119SU is a highly adaptable LCD controller/driver that combines ease of use with powerful display capabilities. Its support for multiple interface options, coupled with its built-in character sets and custom character creation, makes it a top choice for developers looking to enhance the user experience of their products.
