ICM7228AIPIZ

The ICM7228AIPIZ is a 8-digit Microprocessor-compatible LED Display Decoder Driver. The ICM7228 display driver interfaces microprocessors to an 8-digit, 7-segment, numeric LED display. Included on chip are two types of 7-segment decoder, multiplex scan circuitry, LED display segment drivers, LED display digit drivers and an 8-byte static memory as display RAM. Data can be written to the ICM7228A and ICM7228B's display RAM in sequential 8-digit update or in single-digit update format. Data is written to the ICM7228C display RAM in parallel random access format. The ICM7228A drive common anode displays. All versions can display the RAM data as either hexadecimal or code B format.
