CAT1024WI-25-GT3

Supervisors Overview

The CAT1024WI-25-GT3 is a supervisory circuit integrating a 2k-bit serial EEPROM with an I²C interface and a manual reset function. Manufactured by onsemi, it operates within a supply voltage range of 2.7 V to 5.5 V. The device features a 200 ms reset delay time and supports a maximum clock frequency of 400 kHz for the memory interface. It is housed in an SOIC-8 package and is designed for industrial temperature ranges from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a 2k-bit serial EEPROM with I²C bus interface and system power supervisor
• Provides manual reset input capability for controlled system initialization
• Includes brown-out protection to safeguard memory and controllers during power transitions

Supervisors Applications

• Microcontroller-based systems requiring integrated memory and supervision
• Industrial control units operating in extended temperature environments
• Embedded devices needing data retention during power fluctuations

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Check current lifecycle status as end-of-life products may have limited availability. Ensure packaging specifications match application requirements for surface mount installation.

Supervisors Selection Notes

Select this component when a combined supervisory circuit and non-volatile memory solution is required. Verify that the I²C interface compatibility matches the host microcontroller. Ensure the 2.7 V to 5.5 V operating range aligns with the system power supply. Consider the SOIC-8 package constraints for PCB layout design.

Supervisors Part Context

This part belongs to the CAT1024 series, which combines supervisory functions with serial EEPROM memory. It is designed for low-power CMOS applications. The series supports multiple threshold voltage options for various system voltages. It integrates both memory and supervision into a single package to reduce board space.

Supervisors Replacement Considerations

Check for CAT1024YI-25-GT3 (TSSOP-8 package) or CAT1024ZI-25-T3 (MSOP-8 package) if pin-compatible alternatives are needed. Verify functional equivalence regarding I²C interface and reset timing. Confirm package dimensions and thermal characteristics before substitution.
