The ICM7228CIPIZ is an 8-digit, microprocessor-compatible LED display decoder driver designed to interface with 7-segment numeric LED displays. It features on-chip multiplex scan circuitry, segment and digit drivers, and an 8-byte static memory for display RAM. This part operates in a random access format, allowing for flexible data writing. It supports common anode configurations and can display data in both Hexadecimal and Code B formats. The device includes a "No Decode" mode for individual segment control, enabling the direct driving of bargraph and irregular display formats. The ICM7228CIPIZ is suitable for applications in instrumentation, test equipment, and environments where LCD display integrity may be compromised. It operates on a single 5V supply and is RoHS compliant, making it a viable option for engineers seeking a reliable LED display driver.
The Intersil 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.brbr 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 and ICM7228C drive common anode displays. The ICM7228B drives common cathode displays. All versions can display the RAM data as either Hexadecimal or Code B format. The ICM7228A and ICM7228B incorporate 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.brbr The Intersil ICM7228 is an alternative to both the Maxim ICM7218 and the Intersil ICM7218 display drivers. Notice that the ICM7228A/B has an additional single digit access mode. This could make the Intersil ICM7218A/B software incompatible with ICM7228A/B operation.
