The ICM7218BIJI is a 8-digit LED microprocessor-compatible multiplexed display Decoder Driver with marking. The universal LED driver system provides 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 1CM7218B features two control lines which write 8-bit of display input data. Display data is automatically sequenced into the 8-byte internal memory on successive positive going WRITE pulses. Data may be displayed either directly or decoded in Hexadecimal or Code B formats. It features two control lines, 4 separate display data input lines and 3-digit address lines. Display data is written into the internal memory by setting up a digit address and strobing the WRITE line low.
