1/3, 1/4 Duty LCD Display Drivers with Key Input

Function

Overview

The LC75857E and LC75857W are 1/3 duty and 1/4 duty LCD display drivers that can directly drive up to 164

segments and can control up to four general-purpose output ports. These products also incorporate a key scan circuit

that accepts input from up to 30 keys to reduce printed circuit board wiring.

Features

• Key input function for up to 30 keys (A key scan is performed only when a key is pressed.)

• 1/3 duty and 1/4 duty drive schemes can be controlled from serial data.

• 1/2 bias and 1/3 bias drive schemes can be controlled from serial data.

• Capable of driving up to 126 segments using 1/3 duty and up to 164 segments using 1/4 duty.

• Sleep mode and all segments off functions that are controlled from serial data.

• Switching between key scan output and segment output can be controlled from the serial data.

• The key scan operation enabled/disabled state can be controlled from the serial data.

• Switching between segment output port and general-purpose output port can be controlled from serial data.

• The common and segment output waveform frame frequency can be controlled from the serial data.

• Switching between RC oscillator mode and external clock mode can be controlled from the serial data.

• Serial data I/O supports CCB format communication with the system controller.

• Direct display of display data without the use of a decoder provides high generality.

• Independent V

for the LCD driver block.

LCD

(When the logic block supply voltage V_DDis in the range 3.6 to 6.0 V, V_LCDcan be set to a voltage in the range 0.75 × V_DD

to 6.0 V, and when V_DDis in the range 2.7 to 3.6 V, V_LCDcan be set to a voltage in the range 2.7 to 6.0 V.)

• Provision of an on-chip voltage-detection type reset circuit prevents incorrect displays.

Any and all SANYO products described or contained herein do not have specifications that can handle

applications that require extremely high levels of reliability, such as life-support systems, aircraft's

physical and/or material damage. Consult with your SANYO representative nearest you before using

any SANYO products described or contained herein in such applications.

SANYO assumes no responsibility for equipment failures that result from using products at values that

exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other

parameters) listed in products specifications of any and all SANYO products described or contained

herein.
