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.
