Semiconductor Bussiness Headquarters TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110 JAPAN Asynchronous Silicon Gate 1/2 Duty LCD Driver with On-Chip Key Input Function LC75852E, 75852W 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 without decoder intervention • Reset pin that can establish the initial state.
