TC55471 240x64 Controller Description

The TC55471 is an intelligent LCD controller with an integrated touch screen control that supports Kyocera Display (former Optrex) F-55471 Series 240x64 COG Monochrome STN Graphic LCDs. This controller allows user to individually control each display pixel. This independent pixel control allows displaying both text and pictures simultaneously. The TC55471 uses an ATMEGA32 microcontroller and a 4M bit AT45DB041B Flash. The microcontroller can be reprogrammed at any time by using AVRISP device. This board requires a single regulated 3.3VDC 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 TC55471 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.
