Overview
The LC75893M is a 1/3 duty LCD display driver that can
directly drive up to 48 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 20 keys to reduce printed circuit board wiring.
Features
Key input function for up to 20 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 48 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.
