Sharp LH155BA
The LH155BA is an LCD driver with a built-in RAM suitable for driving medium/small scale dot-matrix LCD panels, and which is capable of being directly connected to the bus line of a microcomputer. The LH155BA stores in the RAM the 8-bit parallel or serial display data transferred from the microcomputer and generates LCD drive signals. The LH155BA has 128 segment outputs and 64 common outputs in a single chip, making it possible to create an LCD system with the fewest number of the chips.| Part No. | LH155BA |

DESCRIPTION
Since the LH155BA features a bit-map type LCD driver that one bit of data in the display RAM corresponds to one dot in the LCD, there is a lot of freedom in displaying. The LH155BA enables an LCD system for batteryoperated, hand-carrying information equipment by securing lower power consumption and wider operating voltage range. 128-Segment and 64-Common Outputs LCD Driver IC with A Built-in RAM● Abundant command functions – Display data read/write – Setting up LCD alternating signal cycle – Setting up display starting-line : per line – Display ON/OFF – Display control of normal and reverse modes – Increment control of display RAM address – Write control of read modifying – Internal register read – Power saving mode
● LCD drive power circuit – Built-in booster circuit : Two, three or four times voltage boost is possible – Built-in voltage converter : Generates LCD drive voltages (V0, V1, V2, V3 and V4) based on the boosted voltage – Built-in power bias ratio : 1/7 or 1/9 b...
