LC75842E

Ordering number : EN4966A CMOS LSI LC75842E General-Purpose 1/2 Duty LCD Display Driver Overview The LC75842E is a 1/2 duty general-purpose LCD display driver for applications such as microprocessor-controlled electronic tuning. It can drive up to 54 segments directly. Package Dimensions unit: mm 3162B-QFP36 [LC75842E] Features 1/2 duty, 1/2 bias drive of up to 54 segments Serial data input supports CCB* format communication with the system controller. Backup function which is based on a power saving mode and all segments off functions that are controlled by serial data. High generality, since display data is displayed directly without decoder intervention. The display can be forced to the off state with the INH pin. RC oscillator circuit CCB is a trademark of SANYO ELECTRIC CO., LTD. CCB is SANYO’s original bus format and all the bus addresses are controlled by SANYO.
