CMOSThe 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.
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. Drives 128 Segments Per Package May Be Used with the Following LCDs: Segmented Alphanumeric,
Bar Graph, Dot Matrix, Custom Quiescent Supply Current: 30 A @ 2.7 V VDD Operating Voltage Range: 2.7 to 5.5 V Operating Temperature Range: -40 to 85¡C Separate Access to LCD Drive Section’s Supply Voltage to Allow for Tem-
perature Compensation See Application Notes AN1066 and AN442
