LC75852E

Ordering number : EN4828A CMOS LSI LC75852E, 75852W Asynchronous Silicon Gate 1/2 Duty LCD Driver with On-Chip Key Input Function 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. Package Dimensions unit: mm 3159-QFP64E [LC75852E] 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 without decoder intervention Reset pin that can establish the initial state.
