MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC145003/D Product Preview CMOS 128 Segment LCD Drivers The MC145003/5004 are 128 segment, multiplexed by four LCD Drivers.
The two devices are functionally the same except for their data input protocols.
The MC145003 uses an SPI data input protocol which is directly compatible with that of the MC6805 family of microcomputers.
Using a minimal amount of software (see example), the device may be interfaced to

* o 2/3 VLCD. When a frontplane driver is on, its output switches from 0 V to VLCD, and when it is off, it switches from 2/3 VLCD to 1/3 VLCD. The LCD drive and timing section provides the multiplex signals and backplane driver input signals and formats the frontplane and backplane waveforms. It also
