Note: These are stress ratings only. Stresses exceeding the range specified under Absolute Maximum Ratings may cause substantial damage to the device. Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability.

HT0610 contains circuitry to protect the inputs against damage due to high static voltages or electric fields; however, it is advised that normal precaution to be taken to avoid application of any voltage higher than maximum rated voltages to this high impedance circuit . For proper operation it is recommended that V_IN and Vout be constrained to the range VSS < or = (V_IN or V_OUT) < or = VDD. Reliability of operation is enhanced if unused inputs are connected to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open. This device may be light sensitive? caution should be taken to avoid exposure of this device to any light source during normal operation. This device is not radiation protected.

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 33120 bits. HT0610 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.
