TC51900 320x240 LCD Controller Description

The TC51900 is an intelligent 320x240 LCD controller with integrated touch screen control that provides the Graphical User Interface (GUI) for connecting Kyocera Display (former Optrex) F-51900 (F-51900NCU-FW-ADN, F-51900NCU-FW-ACN) 320x240 CSTN Transmissive Color Graphic LCD display with the target development board. This controller allows user to individually control each display pixel. This independent pixel control allows user displaying both text and graphics simultaneously. The TC51900 utilizes ATMEGA325 microcontroller, S1D13706 color/monochrome LCD graphics controller and external 8Mbit serial flash. The device can be used as an “intelligent” LCD controller or as stand-alone controller. There is enough of flash and RAM memory in the controller on board to incorporate additional graphical commands or to customize the firmware for particular tasks.
