ICM7228CIBI

Display Drivers Overview

The ICM7228CIBI is an LED display driver manufactured by Renesas Electronics Corporation, designed for driving 8-digit, 64-segment displays. It operates within a supply voltage range of 4 V to 6 V and features a maximum power supply current of 450 uA. The component supports surface-mount installation in a SOIC-Wide-28 package and functions reliably across a temperature range of -40°C to +85°C.

Display Drivers Feature Summary

• Supports direct driving of 8-digit, 64-segment LED displays without external crystal oscillators
• Integrates 8x8 bit RAM, segment drivers, decode logic, and multiplexing capabilities
• Enables mode switching via the MODE/SHUTDOWN pin configuration to reduce MCU GPIO usage

Display Drivers Applications

• Embedded systems requiring low-power LED numeric display interfaces
• Industrial control panels with limited microcontroller pin availability
• Portable electronic devices operating on regulated DC power supplies

Display Drivers Procurement Notes

Verify RoHS compliance status directly with the manufacturer or authorized distributors, as documentation indicates potential variations. Confirm current availability and lead times through official channels, noting that specific variants may be subject to discontinuation notices or limited stock constraints. Ensure ordering suffixes match required package types and temperature ranges.

Display Drivers Selection Notes

Select this variant for applications requiring CMOS technology with low quiescent current consumption. Consider the interface compatibility with 3.3V microcontrollers, as data inputs support these logic levels without level shifting. Evaluate the need for dual-bank RAM functionality if dynamic display updates are required, distinguishing it from simpler A/B series variants.

Display Drivers Part Context

This component belongs to the ICM7228 series of LED display drivers produced by Renesas Electronics Corporation, formerly Intersil. The series represents a family of specialized integrated circuits optimized for driving multi-digit seven-segment displays using multiplexing techniques. These devices are widely recognized for their integration of decoding and memory functions into a single chip.

Display Drivers Replacement Considerations

Publicly confirmed substitute part numbers include ICM7228BIBIZ and ICM7228AIBIZ. Verify functional equivalence regarding pinout and electrical characteristics before substitution.
