TC55472 Controller Description

The TC55472 is an intelligent LCD controller with an integrated touch screen control that supports Optrex F-55472 Series 128x64 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 TC55472 uses an ATMEGA16 microcontroller and external AT24C512 serial EEPROM. The microcontroller can be reprogrammed at any time by using AVRISP device. This board requires a single 3.3 VDC supply to be plugged into J5 connector (bypass voltage regulator) or 5-9 VDC power supply to be plugged into J11 connector.
