1 / 14 page Product Preview 128 Segment LCD Drivers CMOS The MC145003/5004 are 128–segment, multiplexed–by–four LCD Drivers. The two devices are functionally the same except for their data input proto- cols. The MC145003 uses an SPI data input protocol which is directly com- patible with that of the MC6805 family of microcomputers. Using a minimal amount of software (see example), the device may be interfaced to the MC68HCXX product families. The MC145004 has a IIC interface and has es- sentially the same protocol, except that the device sends an acknowledge bit back to the transmitter after each eight–bit byte is received. MC145004 also has a “read mode”, whereby data sent to the device may be retrieved via the IIC bus. The MC145003/MC145004 drives the liquid–crystal displays in a multi- plexed–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) communication link which can be common with other MC145003/MC145004 and/or other peripheral devices. • Drives 128 Segments Per Package • Devices May Be Cascaded for Larger LCD Applications • May Be Used with the Following LCDs: Segmented Alphanumeric, Bar Graph, Dot Matrix, Custom • Quiscent Supply Current: 85 µA @ 2.8 V VDD • Operating Voltage Range: 2.8 to 5.5 V • Operating Temperature Range: – 40 to 85°C • Separate Access to LCD Drive Section’s Supply Voltage to Allow for Temperature Compensation • See Application Notes AN1066 and AN442 This document contains information on a new product under development.
