LC75893M Overview
ENN5971A CMOS IC LC75893M 1/3 Duty LCD Display Driver with Key Input Function 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. mm 3204-MFP36S [LC75893M] 36.
LC75893M Key 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 munication 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
