ICM7218BIJIR5254

Display Drivers Overview

The ICM7218BIJIR5254 is an 8-digit LED microprocessor-compatible multiplexed display decoder driver manufactured by Renesas Electronics Corporation. It integrates an 8-byte static display memory, two types of 7-segment decoders (Hexadecimal and Code B), multiplex scan circuitry, and high-current digit and segment drivers for common cathode or common anode displays. The device operates on a single 5V supply with data retention down to 2V and features a shutdown mode for low power dissipation.

Display Drivers Feature Summary

• Microprocessor-compatible interface supporting sequential and random access modes
• Integrated 8-byte static display memory for data retention
• Dual 7-segment decoding capability for Hexadecimal and Code B formats
• Built-in multiplex scan circuitry and high-current output drivers

Display Drivers Applications

• Digital panel meters
• Industrial control systems
• Consumer electronics displays

Display Drivers Procurement Notes

Verify the specific suffix R5254 against official Renesas documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status as historical Intersil/Renesas variants may differ. Ensure compatibility with existing PCB footprints for the CDIP-28 package before procurement.

Display Drivers Selection Notes

Select this component when a complete solution for driving 8-digit 7-segment LEDs is required without external logic. It is suitable for designs needing integrated decoding and scanning. Consider the 5V operating voltage requirement and ensure the host system supports the necessary serial or parallel interface protocols defined in the datasheet.

Display Drivers Part Context

This part belongs to the ICM7218 series of universal LED driver systems originally developed by Intersil and now produced by Renesas. The series provides a single-package solution for interfacing microprocessors to LED displays, eliminating the need for separate decoder and driver ICs.
