ICM7218AIJI

Display Drivers Overview

The ICM7218AIJI is a CMOS LED display driver manufactured by Renesas Electronics Corporation, housed in a 28-pin Ceramic Dual In-Line Package (CDIP). It functions as an 8-digit, 7-segment multiplexed decoder and driver with integrated RAM. The device operates on a single 5V power supply within an industrial temperature range of -40°C to +85°C. Key electrical characteristics include a maximum supply current of 10 µA and a supply voltage range of 4V to 6V. The component supports parallel data input and direct driving of common-cathode or common-anode LED displays without requiring external oscillators.

• Supports 8-digit, 7-segment LED multiplexing with decimal point control
• Features low-power CMOS construction with minimal supply current consumption
• Includes built-in decode logic eliminating the need for external decoding components

Display Drivers Applications

• Industrial instrumentation panel displays
• Commercial digital metering systems
• Embedded control unit status indicators
• Automotive dashboard information modules

Display Drivers Procurement Notes

Verify RoHS compliance status carefully, as documentation indicates non-compliance for this specific part number variant. Confirm package authenticity against the 28-CDIP specification. Check for End-of-Life notices, as related variants have been discontinued. Ensure compatibility with existing 5V logic levels and verify that the ceramic package meets thermal requirements for the target application environment.

Display Drivers Selection Notes

Select this component when a robust ceramic package is required for harsh environments compared to plastic alternatives. Consider the low standby current for battery-backed or power-sensitive applications. Evaluate the 5V logic requirement against the system's microcontroller output levels. Verify that the 8-digit capacity matches the display architecture needs before choosing over smaller segment drivers.

Display Drivers Part Context

This component belongs to the ICM7218 family of LED display drivers originally developed by Intersil and later acquired by Renesas. The 'AI' suffix typically denotes specific pinout configurations or internal logic variations within the series. The CDIP package offers superior thermal stability and hermetic sealing compared to standard plastic DIP versions, making it suitable for high-reliability industrial deployments.
