CMOS

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

ers. The MC14LC5002 is the same as MC14LC5003 except for 72 segments.

The three devices are functionally the same except for their data input pro-

tocols. The MC14LC5002/5003 use a serial interface data input protocol. The

devices 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 MC14LC5002/5003/5004 drive the liquid crystal displays in a multi-

plexed-by-four configuration. The devices accept 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) com-

munication link which can be common with other peripheral devices.

The MC14LC5003/5004 are low cost version of MC145003 and MC145004

without cascading function.
