1 / 18 page Overview The LC75834E, LC75834W, and LC75834JE are 1/4-duty general-purpose LCD drivers that can be used for frequency display in electronic tuners under the control of a microcontroller. The LC75834E and LC75834W can drive an LCD with up to 136 segments directly, the LC75834JE can drive an LCD with up to 120 segments directly. The LC75834E and LC75834W and LC75834JE can also control up to 8 general-purpose output ports. Since the LC75834E, LC75834W, and LC75834JE use separate power supply systems for the LCD drive block and the logic block, the LCD driver block power-supply voltage can be set to any voltage in the range 2.7 to 6.0 volts, regardless of the logic block power-supply voltage. Features • Supports both 1/4 duty 1/2 bias and 1/4 duty 1/3 bias LCD drive under serial data control. LC75834E, LC75834W: up to 136 segments LC75834JE: up to 120 segments (without the S9, S18, S27, S34 segment output pins from the LC75834E, LC75834W) • Serial data input supports CCB* format communication with the system controller. • Serial data control of the power-saving mode based backup function and all the segments forced off function • Serial data control of switching between the segment output port and the general-purpose output port functions • High generality, since display data is displayed directly without decoder intervention. • Independent VLCD for the LCD driver block (VLCD can be set to any voltage in the range 2.7 to 6.0 volts, regardless of the logic block power-supply voltage.) • The INH pin can force the display to the off state. • RC oscillator circuit Package Dimensions unit: mm 3156-QFP48E unit: mm 3163A-SQFP48 unit: mm 3148-QFP44MA [LC75834W] • CCB is a trademark of SANYO ELECTRIC CO., LTD. • CCB is a SANYO’s original bus format and all the bus addresses are controlled by SANYO.
