ICM7211AM

4-Digit, LCD Display Driver

DATASHEET

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.
