128 Segment LCD Drivers

CMOS

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.

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.

communication link which can be common with other MC145003/MC145004

and/or other peripheral devices.
