DATASHEET ICM7218 8-Digit LED Microprocessor-Compatible Multiplexed Display Decoder Driver FN3159 Rev 4.00 May 17, 2016 The ICM7218 series of universal LED driver systems provide, in a single package, all the circuitry necessary to interface most common microprocessors or digital systems to an LED display. Included on-chip are an 8-byte static display memory, two types of 7-segment decoders, multiplex scan circuitry, and high current digit and segment drivers for either common cathode or common anode displays. The lCM7218A and 1CM7218B feature two control lines (WRITE and MODE) which write either 4 bits of control information (DATA COMING, SHUTDOWN, DECODE and HEXA/CODE B) or 8 bits of display input data.
