Manufacturer Part Number
lc75811e
Description
1/8 To 1/10 Duty Dot Matrix Lcd Display Controller/driver
Manufacturer
Sanyo Semiconductor Corporation
Datasheet
Ordering number : EN5915A
Overview
The LC75811E and LC75811W are 1/8 to 1/10 duty dot
matrix LCD display controller/drivers that supports the
display of characters, numbers, and symbols. In addition to
generating dot matrix LCD drive signals based on data
transferred serially from a microcontroller, the LC75811E
and LC75811W also provide on-chip character display ROM
and RAM to allow display systems to be implemented easily.
