LC823425-12G1-H

The LC75853NE and LC75853NW are 1/3 duty LCD display drivers that can directly drive up to 126 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 - 1/2 bias and 1/3 duty - 1/3 bias drive schemes can be controlled from serial data (up to 126 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 communication with the system controller.
• Direct display of display data without the use of a decoder provides high generality.
• Provision of an on-chip voltage-detection type reset circuit prevents incorrect displays.
• RC oscillator circuit
