ICM7228CIPIZ

Display Drivers Overview

The ICM7228CIPIZ is an LED display driver manufactured by Renesas Electronics, 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 device supports serial data input and includes internal RAM for display storage. It is housed in a 28-pin PDIP package with through-hole mounting style. The component functions reliably across an operating temperature range from -40°C to +85°C.

Display Drivers Feature Summary

• Supports direct driving of 8-digit, 64-segment LED displays without external multiplexing circuitry
• Integrates internal RAM for display data storage and built-in oscillator
• Enables single-byte update capability for efficient data transmission
• Compatible with 3.3V logic levels on data input pins for modern microcontroller interfaces

Display Drivers Applications

• Industrial control panels requiring numeric or alphanumeric display
• Embedded systems with limited GPIO resources needing simplified display interfacing
• Consumer electronics utilizing 7-segment LED indicators
• Instrumentation devices displaying measurement values

Display Drivers Procurement Notes

Verify the specific suffix 'C' indicates the correct variant for your application, as it determines pin configuration and mode selection behavior. Confirm that the 28-PDIP package aligns with your PCB layout requirements. Ensure the 4V-6V supply voltage matches your system design, as operation outside this range may affect performance. Check for end-of-life status if long-term availability is critical.

Display Drivers Selection Notes

Select the ICM7228CIPIZ when a through-hole DIP package is required for prototyping or specific mechanical constraints. Choose this variant over surface-mount options if manual assembly or rework capabilities are prioritized. Consider the C-series specific pinout for MODE/SHUTDOWN functionality if dual-bank RAM or single-byte updates are needed. Verify compatibility with existing 3.3V or 5V logic levels before finalizing the design.

Display Drivers Part Context

The ICM7228 series belongs to Renesas' legacy LED driver portfolio, originally developed by Intersil. These components are widely recognized for their simplicity in driving multi-digit 7-segment displays. The CIPIZ designation specifies the industrial temperature grade and PDIP packaging. This part is part of a broader family including A, B, and D variants, differentiated by control signal configurations and feature sets like dual-bank RAM support.

Display Drivers Replacement Considerations

ICM7228BIBIZ: Surface-mount SOIC-Wide-28 equivalent with similar electrical characteristics but different package type. ICM7228AIBIZ: Alternative variant with distinct control pin mapping; verify interface compatibility before substitution.
