onsemi Supervisory Circuits CAT1025YI-28-GT3

The CAT1025YI-28-GT3 is a supervisory circuit integrated with a 2k-bit EEPROM memory, designed for microcontroller-based systems. It operates within a voltage range of 2.7 V to 5.5 V and features a 400 kHz I¬=C bus interface. The device includes a precision power supply voltage monitor with five selectable threshold options, supporting 5 V, 3.3 V, and 3 V systems. It provides both active high and low reset outputs, ensuring valid reset signals at a minimum V_CC of 1 V. The CAT1025YI-28-GT3 incorporates a manual reset input and a write protect feature, which disables write operations when the WP pin is high. It is built using low power CMOS technology, offering a data retention period of up to 100 years and supporting 1,000,000 program/erase cycles. The device is available in various packages, including an 8-pin TSSOP, making it suitable for space-constrained applications. The operational temperature range is industrial, from -40¬8C to 85¬8C, ensuring reliability in demanding environments.
