General Description

The HT0610 is a driver and controller LSI for graphic dot-matrix liquid crystal display systems. It has 33 common and 120 segment driver circuits. This chip is connected directly to an MCU, accepts 8-bit parallel display data and stores an on-chip graphic display data RAM (BGDRAM) of 33 x 120 bits. It provides a high-flexible display section due to the one-to-one correspondence between BGDRAM bits and LCD panel pixels. It performs BGDRAM read/write operation with no externally operating clock to minimize power consumption. In addition, because it contains power supply circuits necessary to drive an LCD, it is possible to make a display system with minimal components.
