LC75852W

Ordering number : EN4828A LC75852E LC75852W CMOS LSI Asynchronous Silicon Gate 1/2 Duty LCD Driver with On-Chip Key Input Function http://onsemi.com 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 communication with the system controller.  High generality since display data is displayed directly...
