ICM7228BIPIZ

Display Drivers Overview

The ICM7228BIPIZ is an 8-digit, 64-segment LED display driver manufactured by Renesas Electronics. It operates on a single 4V to 6V power supply with a maximum supply current of 450 µA. The device supports serial data input and includes an internal 8x8 RAM for display storage. It features built-in decode logic, segment drivers, and bit drivers to directly drive common-cathode or common-anode LED displays. The component is available in a 28-pin PDIP package and is rated for an industrial operating temperature range from -40°C to +85°C.

Display Drivers Feature Summary

• Supports direct driving of 8-digit, 7-segment LED displays including decimal points without external decoding components
• Integrates 8x8 static RAM for display data storage and shift register functionality for serial data entry
• Includes built-in BCD-to-decimal decode logic and high-current segment drivers for direct LED interfacing
• Features shutdown mode for significant power reduction and multiplexing capability for efficient display scanning

Display Drivers Applications

• Industrial control panel numeric displays
• Test and measurement equipment readouts
• Consumer appliance status indicators
• Embedded system user interfaces

Display Drivers Procurement Notes

Verify the exact suffix 'BIPIZ' against the manufacturer's official datasheet to confirm pinout compatibility and RoHS status. Check current availability as this series may be subject to discontinuation notices. Ensure the procurement source provides valid traceability documentation for industrial grade components.

Display Drivers Selection Notes

Select this part when designing systems requiring simple serial interface control for multi-digit LED displays. It is suitable for applications where low power consumption is critical and direct segment driving eliminates the need for external transistor arrays. Consider the 28-PDIP package for through-hole prototyping or manufacturing requirements.

Display Drivers Part Context

The ICM7228 belongs to the Intersil/Renesas family of LED display controllers, originally designed for cost-effective numeric display solutions. It complements other variants like the ICM7218 by offering enhanced decode capabilities and integrated RAM. The BIPIZ suffix typically denotes a specific package type and environmental compliance standard within the broader ICM7228 product line.
