CAT1023WI25

Supervisors Overview

The CAT1023WI-25 is a supervisory circuit integrating a 2k-bit I²C serial EEPROM and a voltage monitor. It operates within a supply voltage range of 2.7 V to 5.5 V with a threshold of 2.5 V. The device features a watchdog timer, manual reset input, and active high/low reset outputs. It supports a 400 kHz I²C bus and includes a 16-byte page write buffer. Available in SOIC-8 packages, it ensures data retention for 100 years and withstands 1,000,000 program/erase cycles.

Supervisors Feature Summary

• Integrates a 2k-bit I²C serial EEPROM with system power supervisor
• Includes watchdog timer and manual reset functionality
• Provides brown-out protection with guaranteed reset at low voltages
• Features built-in inadvertent write protection mechanisms

Supervisors Applications

• Microcontroller-based systems requiring memory and supervision
• Industrial control units needing reliable power monitoring
• Consumer electronics with embedded data storage needs

Supervisors Procurement Notes

Verify the exact suffix (e.g., -T3) for packaging details such as reel or tube quantities. Confirm RoHS compliance status and lead times directly with onsemi or authorized distributors. Ensure the specific package variant matches your PCB footprint requirements before ordering.

Supervisors Selection Notes

Select this component when both non-volatile memory and power supervision are required in a single package. Compare threshold voltage options against your system's operating voltage. Consider package availability and temperature range specifications relative to your application environment.

Supervisors Part Context

Part of the CAT102x family including CAT1021 and CAT1022 variants. These devices combine EEPROM memory with supervisory functions for microcontroller systems. The series offers various threshold voltages and package options to suit different design constraints.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the CAT102x series. Verify if alternative manufacturers offer equivalent I²C EEPROM supervisors with similar threshold characteristics.
