Overview
The LC75852E and LC75852W are 1/2 duty dynamic
LCD display drivers. In addition to being able to directly
drive LCD panels with up to 90 segments, they can also
control up to four general-purpose output ports. These
products also include a key scan circuit which allows
them to accept input from keypads with up to 30 keys.
This allows end product front panel wiring to be
simplified.
