128 Segment LCD Drivers

CMOS

The MC14LC5003/5004 are 128-segment, multiplexed-by-four LCD Driv-

ers. 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 acknowl-

edge 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 mul-

tiplexed-by-four conﬁguration. The device accepts data from a microproces-

sor 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.

PIN ASSIGNMENT

Devices are independently addressable via a two-wire (or three-wire) com-

munication link which can be common with other peripheral devices.

The MC14LC5003/MC14LC5004 are low cost version of MC145003 and

MC145004 without cascading function.
