Functions
· Supports both 1/3 duty 1/2 bias and 1/3 duty 1/3 bias LCD driver techniques for a maximum of 156 segments. · Power saving mode allows the backup function to be switched on or off and all segments to be turned off unconditionally. · Can be controlled by three serial data lines (CE, CL, and DI) from the microprocessor. (CCB handling) · High generality, since segment data can be displayed without going through a decoder. · The INH pin unconditionally turns off display. · The LCD drive bias voltage can be provided internally or externally. · Power supply voltage: 4.5 to 8V.
