CAT1026YI-28-GT3

Supervisors Overview

The CAT1026YI-28-GT3 is a 1Kb (128 x 8) Serial Electrically Erasable PROM manufactured by onsemi. It operates within a voltage range of 2.5V to 5.5V and supports standard I2C interface protocols with clock frequencies up to 400kHz in fast mode. The device features a hardware write protect pin, an internal write cycle timer, and automatic page write functionality for enhanced data integrity. Packaged in a compact 8-pin SOIC format, it ensures reliable non-volatile storage for embedded systems requiring low power consumption and robust data retention.

Supervisors Feature Summary

• Supports high-speed I2C communication with hardware write protection capabilities
• Includes internal write cycle timer to ensure complete data programming without external monitoring
• Offers automatic page write functionality to optimize bus efficiency during bulk data transfers

Supervisors Applications

• Configuration storage in consumer electronics
• Calibration data retention in industrial sensors
• User setting memory in embedded control systems

Supervisors Procurement Notes

Verify the specific suffix GT3 indicates tape and reel packaging when ordering. Confirm the operating temperature range matches your environmental requirements. Ensure the I2C address configuration aligns with your system design constraints before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a small capacity non-volatile memory solution is required for I2C-based architectures. Consider the 1Kb density for applications needing minimal storage space. Evaluate the 2.5V minimum supply voltage against your system's power rails to ensure compatibility.

Supervisors Part Context

This part belongs to the CAT1026 family of serial EEPROMs designed for cost-sensitive applications. It shares architectural similarities with other members but differs in package type and packaging quantity. The YI suffix denotes the industrial temperature grade and SOIC package style.

Supervisors Replacement Considerations

Direct substitutes include other CAT1026 variants with compatible I2C interfaces. Verify pinout compatibility before swapping. Alternative manufacturers offer functionally similar devices, but electrical specifications must be cross-referenced carefully.
