FN3160 Rev 9.00 Page 1 of 19 August 19, 2015 FN3160 Rev 9.00 August 19, 2015 ICM7228 8-Digit, Microprocessor-Compatible, LED Display Decoder Driver DATASHEET 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. 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. 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. Features • Pb-Free Plus Anneal Available (RoHS Compliant) • Improved 2nd Source to Maxim ICM7218 • Fast Write Access Time of 200ns • Multiple Microprocessor Compatible Versions • Hexadecimal, Code B and No Decode Modes • Individual Segment Control with “No Decode” Feature • Digit and Segment Drivers On-Chip • Non-Overlapping Digits Drive • Common Anode and Common Cathode LED Versions • Low Power CMOS Architecture • Single 5V Supply Applications • Instrumentation • Test Equipment • Hand Held Instruments • Bargraph Displays • Numeric and Non-Numeric Panel Displays • High and Low Temperature Environments where LCD Display Integrity is Compromised
