LC75835W ^{1/3, 1/4-Duty General-Purpose}
LCD Display Driver
Overview
The LC75835W is a 1/3, 1/4 duty general-purpose LCD display driver that can be used for displaying segments for
mobile devices and other such products under the control of a microcontroller. In addition to being able to directly drive
up to 136 LCD segments, the LC75835W can also control up to 16 general-purpose output ports. It incorporates an
oscillation circuit that reduces the external resistors and capacitors used for oscillation.
Features
• Either 1/4 or 1/3 duty can be selected with the serial control data.
1/4 duty drive: Up to 136 segments can be driven
1/3 duty drive: Up to 105 segments can be driven
• Either 1/3 or 1/2 bias can be selected with the serial control data.
• On, off, or blinking for each segment can be set with the serial control data.
• Serial data control of display switching in 40-bit units.
(As a general rule, the display can be switched in 12 segment-units.)
• Serial data control of current on/off to the LCD drive bias voltage generation divider resistors.
• Serial data control of the power-saving mode based backup function and the all segments forced off function.
• Serial data control of switching between the segment output port and general-purpose output port functions.
• Buzzer control signals (1 channel) can be output from the general-purpose output port.
• Serial data control of the frame frequency of the common and segment output waveforms.
• Serial data control of the segment blinking frequency.
• Serial data control of switching between the internal oscillator operating mode and external clock operating mode.
• Serial data input supports CCB* format communication with the system controller.
• Independent VLCD for the LCD driver block (VLCD can be set to any voltage in the range 2.7 to 5.5 volts without
regard to the logic block power supply VDD).
• The INH pin allows the display to be forced to the off state.
• Incorporation of an 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.
