General Description

The EM65101 is an LCD controller for 16-level gray scale graphic dot-matrix liquid

crystal display system. It is a (160 x 128) for segment and common driver circuit. It has

a built-in display RAM, a power supply circuit for LCD driver. It also supports EEPROM

function for programming information to tune the VLCD offset voltage to get the best

contrast which helps in compacting system design. Its “partial display”

1 function

realizes results in low power consumption.
