onsemi LC75852W
The LC75852E and LC75852W are 1/2 duty dynamic LCD display drivers. 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.FEATURES
● Up to 30 key inputs (Key scan is only performed when a key is pressed.)● 1/2 duty – 1/2 bias (up to 90 segments)
● Sleep mode and the all segments off function can be controlled from serial data.
● Segment output port/general-purpose output port usage can be controlled from serial data.
● Serial data I/O supports CCB format communication with the system controller.
● High generality since display data is displayed directly
