TC405/851 Controller Description

The TC405/851 is an intelligent LCD controller with an integrated touch screen control that supports Optrex F-51405 and F-51851 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 TC405/851 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 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.
