LC75852E: LCD Driver, 1/2 Duty, with Key Input
The LC75852E is 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.
特性- 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.
