The MC14LC5003/5004 are 128-segment, multiplexed-by-four LCD Drivers. The MC14LC5002 is the same as MC14LC5003 except for 72 segments. The three devices are functionally the same except for their data input protocols. 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 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.
