DESCRIPTION

· The ICM7218 series is a universal LED driver system designed to interface microprocessors or digital systems with LED displays.

· It integrates an 8-byte static display memory, 7-segment decoders, multiplex scan circuitry, and high current drivers for both common anode and cathode displays.

· Models ICM7218A/B use two control lines for data and control information, while ICM7218C/D feature separate data input and digit address lines.

FEATURES

· Microprocessor compatible with full on-chip circuit integration.

· Includes digit and segment drivers, multiplex scan circuitry, and 8-byte static display memory.

· Supports Hexadecimal and Code B decoding formats.

· Operates on a single 5V supply with data retention down to 2V.

· Features a shutdown mode for low power consumption.

APPLICATIONS

· Suitable for direct drive of LED displays in both common anode and cathode configurations.

· Ideal for use in digital systems requiring sequential or random access display updates.

· Can be used in systems where low power consumption and data retention are critical.
