General Description
Feature
EM65570S is one of the industry’s most advanced wide-screen STN-LCD drivers for
65K-color display. It also has a built-in display RAM, a power supply circuit for LCD
drive, an LCD controller circuit, support for LCD cell tolerance compensation of VLCD
and temperature compensation. It also supports OTP function for programming
information to tune VLCD offset voltage to get the best contrast, hence enhancing the
compact system design. Its partial display function”
