Overview

TM ICM7231, ICM7232 Numeric/Alphanumeric Triplexed LCD Display Drivers Description The ICM7231 and ICM7232 family of integrated circuits are designed to generate the voltage levels and switching waveforms required to drive triplexed liquid-crystal displays.
These chips also include input buffer and digit address decoding circuitry allowing six bits of input data to be decoded into 64 independent combinations of the output segments of the selected digit.
The family is designed to interface to modern highperformance microprocessors and microcomputers and ease system requirements for ROM space and CPU time needed to service a display.
August 1997 Features • ICM7231 Drives 8 Digits of 7 Segments with Two Independent Annunciators Per Digit Address and Data Input in Parallel Format • ICM7232 Drives 10 Digits of 7 Segments with Two Independent Annunciators Per Digit Address and Data Input in Serial Format • All Signals Required to Drive Rows and Columns of Triplexed LCD Display are Provide...
