1/4 and 1/3-Duty General-Purpose
LC75829PW _{LCD Display Driver}
Overview
The LC75829PE and LC75829PW are 1/4 duty and 1/3 duty general-purpose microprocessor-controlled LCD drivers
that can be used in applications such as frequency display in products with electronic tuning.
In addition to being able to drive up to 208 segments directly, the LC75829PE and LC75829PW can also control up to 4
general-purpose output ports. Incorporation of an oscillation circuit helps to reduce the number of external resistors and
capacitors required.
Features
• Support for 1/4-duty 1/3-bias or 1/3-duty 1/3-bias drive techniques under serial data control.
When 1/4-duty: Capable of driving up to 208 segments
When 1/3-duty: Capable of driving up to 159 segments
• Serial data input supports CCB format communication with the system controller. (Support 3.3V and 5V operation)
• 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 function.
(Support for up to 4 general-purpose output ports)
• Support for clock output function of 1ch.
• Serial data control of the frame frequency of the common and segment output waveforms.
• Serial data control of switching between the internal oscillator operating mode and external clock operating mode.
• High generality, since display data is displayed directly without the intervention of a decoder circuit.
• The INH pin allows the display to be forced to the off state.
• Incorporation of an oscillator circuit. (Incorporation of resistor and capacitor for an oscillation)
• CCB is a registered trademark of SANYO Semiconductor Co., Ltd.
• CCB is SANYO Semiconductor's original bus format. All bus addresses are managed by SANYO
Semiconductor for this format.
