KD83

KD83 is a gray-scale LCD Segment Extender which, when used with KB's MCU with LCD Segment  xtender interface, can expand the capacity of LCD driver. It is a 16 gray-scale, 4 gray-scale, and black and white LCD Segment Driver. This chip interfaces with KB's MCU with provisions of Segment Extender Interface LFR and CCK. KB's MCUs control KD83 through a command interface. The MCU can read/write display patterns to graphic mode display RAM by first setting up the target address, electing the driver  nfiguration, and then enabling the driver. KD83 can support five different LCD configurations: 16, 32, 48, 64 and 80 COM selectable by command register. The KD83 uses some of the memory as display RAM, while the memory not used for display can be access as general-purpose memory.
