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.
