ICM7228BIBIZ

ICM7228BIBIZ is an 8-digit, microprocessor-compatible, LED display decoder driver. This 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. This display RAM in sequential 8-digit update or in single-digit update format. The ICM7228B drives common cathode displays. This incorporates a no decode mode allowing each bit of each digit's RAM word to drive individual display segments resulting in independent control of all display segments. As a result, bargraph and other irregular display segments and formats can be driven directly by this chip. Application includes instrumentation, test equipment, hand held instruments, bargraph displays, numeric and non-numeric panel displays and high and low temperature environments where LCD display integrity is compromised.
