ICM7218AIJI (RENESAS)

The ICM7218AIJI is a 8-digit LED microprocessor-compatible Multiplexed Display Decoder Driver. The ICM7218 series of universal LED driver systems provide, 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 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. 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.
