ICM7211AM
4-Digit, LCD Display Driver
The ICM7211AM device is a non-multiplexed four-digit
seven-segment CMOS LCD display decoder-driver.
This device is configured to drive conventional LCD displays
by providing a complete RC oscillator, divider chain,
backplane driver, and 28 segment outputs.
It also has a microprocessor compatible input configuration,
which provides data input latches and Digit Address latches
under control of high-speed Chip Select inputs. These devices
simplify the task of implementing a cost-effective
alphanumeric seven-segment display for microprocessor
systems, without requiring extensive ROM or CPU time for
decoding and display updating.
The ICM7211AM provides the “Code B” output code, i.e.,
0-9, dash, E, H, L, P, blank, but will correctly decode true
BCD to seven-segment decimal outputs.
Features
• Four Digit Non-Multiplexed 7 Segment LCD Display
Outputs with Backplane Driver
• Complete Onboard RC Oscillator to Generate Backplane
Frequency
• Backplane Input/Output Allows Simple Synchronization of
Slave-Devices to a Master
• Provides Data and Digit Address Latches Controlled by
Chip Select Inputs to Provide a Direct High Speed
Processor Interface
• Decodes Binary to Code B (0-9, Dash, E, H, L, P, Blank)
• Pb-Free Plus Anneal Available (RoHS Compliant)

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.
*Pb-free PDIPs can be used for through hole wave solder processing only. They are not intended for use in Reflow solder processing applications.

*Pb-free PDIPs can be used for through hole wave solder process-
ing only. They are not intended for use in Reflow solder processing
applications.
CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. Due to the SCR structure inherent in the CMOS process, connecting any terminal to voltages greater than V
DD
or less than V
SS
may cause
destructive device latchup. For this reason, it is recommended that no inputs from external sources not operating on the same power supply be
applied to the device before its supply is established, and that in multiple supply systems, the supply to the ICM7211AM be turned on first.
2.
