8-Digit, Microprocessor-Compatible, LED
Display Decoder 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.
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.

*Pb-free PDIPs can be used for through hole wave solder processing only. They are not intended for use in Reflow solder processing applications.
NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are
MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
