Product Summary

The ICM7228BIBIZ is an 8-digit, microprocessor-compatible, led display decoder driver. The ICM7228BIBIZ 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. The Intersil ICM7228BIBIZ is an alternative to both the Maxim ICM7228BIBIZ and the Intersil ICM7228BIBIZ display drivers. Notice that the ICM7228BIBIZ has an additional single digit access mode. This could make the Intersil ICM7218A/B software incompatible with ICM7228BIBIZ operation.
