MC145004 - (MC145003 / MC145004) 128 Segment LCD Drivers

Download the MC145004 datasheet PDF. This datasheet also covers the MC145003FU variant, as both devices belong to the same (mc145003 / mc145004) 128 segment lcd drivers family and are provided as variant models within a single manufacturer datasheet.

General Description

section.

Frontplanes VO = 0.15 V VO = 2.65 V VO = 1.72 V VO = 1.08 V VO = 0.15 V VO = 5.35 V VO = 3.52 V VO = 1.98 V Supply Currents (fOSC) = 110 kHz IDD = Quiescent @ Iout = 0 µA ILCD = Qu

Key Features

  • 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 provides a “frame sync” pulse which may be used in a system where many LCD drivers are cascaded, to synchronize the backplanes/frontplanes of all participating LCD drivers. The address pins are used i.

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 the MC68HCXX product families. The MC145004 has a IIC interface and has essentially the same protocol, except that the device sends an acknowledge bit back to the transmitter after each eight–bit byte is received. MC145004 also has a “read mode”, whereby data sent to the device may be retrieved via the IIC bus.
