ICM7218
FN3159.3
8-Digit LED Microprocessor-Compatible Multiplexed Display Decoder Driver
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.
