TC405/851 240x64 LCD Controller Description


The TC405/851 is an intelligent 240x64 LCD controller with integrated touch screen control that provides the Graphical User Interface (GUI) for connecting Kyocera Display (former Optrex) F-51405 and F-51851 Series 240x64 COG Monochrome STN Graphic LCD displays with the target development board. This controller allows user to individually control each display pixel. This independent pixel control allows displaying both text and pictures simultaneously. The TC405/851 uses an ATMEGA32 microcontroller and a 4M bit AT45DB041B Flash. The controller can be used as a development board and reprogrammed via AVRISP device or OEM. This board requires a single regulated 5 VDC supply to be plugged into J12 connector (bypass voltage regulator) or 7-20 VDC power supply to be plugged into J8 or J9 (optional) connectors.

TouchScreen Controller

The TouchScreen controller can respond by sending XY coordinates of touch screen contact location or by sending digits (if used as a 6x3 keypad) to main microprocessor or computer. The TC405/851 LCD controller has a built-in buzzer which can produce a sound on touch. In 6x3 Keypad Mode, the screen is divided on 18 boxes 37x18 pixels each. Each box response can be disabled or enabled. Touch screen controller if used in 6x3 Keypad Mode provides a Flip option which reverses colors of the touched box.
