CAT1022ZI-30-GT3

Supervisors Overview

The CAT1022ZI-30-GT3 is a serial EEPROM memory device manufactured by onsemi. It features a 2-kbit (256 x 8) storage capacity organized in a page-write architecture. The component operates with a supply voltage range of 1.8V to 5.5V and supports an I²C-compatible two-wire serial interface for data communication. It includes hardware write protection via the WP pin and offers high endurance specifications for industrial applications.

Supervisors Feature Summary

• Supports I²C-compatible two-wire serial interface for efficient data transfer
• Hardware write protection mechanism ensures data integrity
• Page-write architecture optimizes sequential data operations

Supervisors Applications

• Industrial control systems requiring non-volatile parameter storage
• Automotive electronics for configuration data retention
• Consumer devices needing compact memory solutions

Supervisors Procurement Notes

Verify the specific suffix 'GT3' against official datasheets to confirm tape-and-reel packaging requirements. Ensure the operating voltage aligns with system rails, as the device supports 1.8V to 5.5V. Cross-reference lead times and availability through authorized distributors, noting that older revisions may have limited stock.

Supervisors Selection Notes

Select this component when a small, low-power serial EEPROM is required for storing calibration data or user settings. The I²C interface minimizes pin count, making it suitable for space-constrained designs. Consider the page-write size for write cycle efficiency and ensure the voltage level compatibility matches the host microcontroller.

Supervisors Part Context

This part belongs to onsemi's CAT1022 series of serial EEPROMs, designed for general-purpose non-volatile memory applications. The series is known for its reliability and low power consumption, fitting into the broader portfolio of standard products used across automotive, industrial, and consumer markets.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the same family, such as other CAT1022 variants with different voltage ranges or package types. Verify functional equivalence if considering third-party alternatives, ensuring I²C compatibility and memory organization match.
