ICM7228  
8-Digit, Microprocessor-  
Compatible, LED Display Decoder Driver  
August 1997  
Features  
Description  
• Improved 2nd Source to Maxim ICM7218  
• Fast Write Access Time of 200ns  
The Intersil ICM7228 display driver interfaces microproces-  
sors 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.  
• 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  
Data can be written to the ICM7228A and ICM7228B’s display  
RAM in sequential 8-digit update or in single-digit update for-  
mat. Data is written to the ICM7228C and ICM7228D display  
RAM in parallel random access format. The ICM7228A and  
ICM7228C drive common anode displays. The ICM7228B and  
ICM7228D drive 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.  
• Common Anode and Common Cathode LED Versions  
• Low Power CMOS Architecture  
• Single 5V Supply  
Applications  
• Instrumentation  
• Test Equipment  
• Hand Held Instruments  
• Bargraph Displays  
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.  
• Numeric and Non-Numeric Panel Displays  
• High and Low Temperature Environments where LCD  
Display Integrity is Compromised
