Overview
MOTOROLA SEMICONDUCTOR TECHNICAL DATA 128 Segment LCD Drivers CMOS The MC14LC5003/5004 are 128-segment, multiplexed-by-four LCD Drivers.
The two devices are functionally the same except for their data input protocols.
The MC14LC5003 uses a serial interface data input protocol.
The device may be interfaced to the MC68HCXX product families using a minimal amount of software (see example).
The MC14LC5004 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.
MC14LC5004 also has a “read mode”, whereby data sent to the device may be retrieved via the IIC bus.
The MC14LC5003/MC14LC5004 drives the liquid-crystal displays in a multiplexed-by-four configuration.
The device accepts data from a microprocessor or other serial data source to drive one segment per bit.
The chip does not have a decoder, allowing for the flexibility of formatting the segment data externally.
Devices are independently addressable via a two-wire (or three-wire) communication link which can be common with other peripheral devices.
The MC14LC5003/MC14LC5004 are low cost version of MC145003 and MC145004 without cascading function.
