ICM7218CIPI

Display Drivers Overview

The ICM7218CIPI+ is an LED display driver manufactured by Analog Devices Inc./Maxim Integrated, designed for multiplexed LED decoder applications. It supports 8-digit displays with a 64-segment configuration, utilizing a parallel interface for data input. The device operates within a supply voltage range of 2 V to 6 V and features a maximum power dissipation of 1 W. It is housed in a PDIP-28 package and functions reliably across a temperature range of -20°C to +85°C.

Display Drivers Feature Summary

• Supports direct driving of 8-digit multiplexed LED displays with integrated decoding logic
• Features a MODE/SHUTDOWN pin that enables tri-state control for hexa or code B decoding modes
• Includes dual RAM banks for efficient data storage and display updates
• Compatible with 3.3V microcontroller logic levels on data input pins

Display Drivers Applications

• Embedded systems requiring 8-digit LED numeric displays
• Industrial instrumentation panels
• Consumer electronics with segment-based readouts

Display Drivers Procurement Notes

Verify the specific suffix (e.g., CIPI+) against the manufacturer's current datasheet to confirm package type and RoHS compliance status. Confirm availability as distribution channels may list limited stock or obsolete status. Ensure the ordering part number matches the required variant for mode selection and electrical specifications.

Display Drivers Selection Notes

Select this component when an 8-digit LED driver with parallel interface and internal decoding is required. The C/D variants offer enhanced mode control via tri-state pins compared to A/B variants. Verify compatibility with the host microcontroller's voltage levels, particularly noting that while data inputs support 3.3V logic, mode control thresholds may require level shifting in some 3.3V systems.

Display Drivers Part Context

The ICM7218 series comprises CMOS LED display drivers originally developed by Intersil and later acquired by Maxim Integrated, now part of Analog Devices. The family includes variants like ICM7218AIQI+ and ICM7218DIQI+, differing primarily in packaging and mode control configurations. The ICM7218CIPI+ represents the commercial grade version in a PDIP package.

Display Drivers Replacement Considerations

ICM7218DIQI+ is listed as a direct replacement for older versions. ICM7218BIJI is noted as a similar alternative from Renesas. Verify pinout and mode control logic compatibility before substitution.
