Ordering number : EN4828A LC75852E CMOS LSI Asynchronous Silicon Gate 1/2 Duty LCD Driver with On-Chip Key Input Function http://onsemi. 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. 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 munication with the system controller. - High generality since display data is displayed...
