LSIs which incorporate 20-bit shift register, latch, and two sets of 20 LCD drivers. They also have two switching pins: one of them (channel 2) can be used as a scan-line driver (back plate) and the other (channel 1) as a segment driver. They are optimal for LCD interface with microcontroller (4 or 8 bits) or dot matrix controller circuit incorporating character generator. Package Dimensions unit : mm 3055A-QFP60C [LC7930N] Features . Two channels of 20 output segment drivers . The configuration of 20 output segment drivers + 20 terminal drivers available . scanning A series data to connect with the microcontroller and thr
