1. Introduction
This User Manual describes the OM6290 LCD Demo board. This board was developed
in order to provide a tool for application engineers and development engineers wishing to
try and evaluate the possibilities of some of our LCD driver IC’s and to get hands-on
experience with writing code for these drivers. Code written using this board can be used
in the final application which enables rapid prototyping. The board can also serve as an
example for the hardware related aspects of a design using NXP LCD drivers.
Features:
Demonstrates how to use NXP LCD drivers
Contains three displays controlled by I

The three drivers all include an I
2
C interface and can be programmed via the onboard
NXP micro controller LPC2148 which is built around an ARM7 core.
The PCF8576D is a Segment Driver and has a lot in common with other NXP Segment
Drivers such as PCF8532 (4 x 160 segments), PCF8533 (4 x 80), PCF8534A (4 x 60),
PCF8562 (4 x 32) and PCF8566 (4 x 24).
The PCF2119 is a Character Driver and has a lot in common with other members of the
family like PCF2113 and PCF2116.
The PCF8531 is a Graphic Driver (Row/Column) and the NXP family of Graphic Drivers
contains some other types like PCF8535. Experiences gained with the onboard drivers
can easily be used for working with the other drivers belonging to the same family.
The 12nc of the OM6290 board is 9352 861 74598.
