onsemi Supervisors CAT1162WI28

The CAT1162WI28 is a supervisory circuit designed for microcontroller-based systems, integrating a 16K serial EEPROM memory with hardware write protection, a power supervisor, and a reset controller. It operates within a voltage range of 2.7 V to 6 V and is compatible with a 400 kHz I2C bus. The device features five reset threshold voltage options suitable for 5 V, 3.3 V, and 3 V systems, ensuring protection against power supply fluctuations and brownout conditions. The reset signals become active when supply voltages are out of tolerance, preventing system operation until conditions are safe. The CAT1162 does not include a watchdog timer, which is available in the CAT1161 variant. The product is available in both 8-pin DIP and surface mount SOIC packages, making it versatile for various applications. It supports 1,000,000 program/erase cycles and offers 100 years of data retention, ensuring reliability in long-term use.
