LC75863W Overview
ENN7135A LC75863W CMOS IC 1/3 Duty LCD Display Driver with Key Input Function http://onsemi. Overview The LC75863W is the 1/3 duty LCD display driver that can directly drive up to 75 segments and can control up to four general-purpose output ports. This product also incorporates a key scan circuit that accepts input from up to 30 keys to reduce printed circuit board wiring.
LC75863W Key Features
- Key input function for up to 30 keys (A key scan is performed only when a key is pressed.)
- 1/3duty
- 1/2bias and 1/3duty
- 1/3bias drive schemes can be controlled from serial data (up to 75 segments)
- Sleep mode and all segments off functions that are controlled from serial data
- Segment output port/general-purpose output port function switching that is controlled from serial data
- Serial data I/O supports CCB format munication with the system controller
- Direct display of display data without the use of a decoder provides high generality
- Independent VLCD for the LCD driver block (VLCD can be set to in the range VDD-0.5 to 6.0 volts.)
- Provision of an on-chip voltage-detection type reset circuit prevents incorrect displays
