onsemi Supervisors CAT1162WI30

The CAT1162WI30 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 can be configured as active high or low, facilitating easy interfacing with microcontrollers and other integrated circuits. The CAT1162 does not include a watchdog timer, which is available in the CAT1161 variant. The product is offered in both 8-pin DIP and surface mount SOIC packages, making it versatile for various applications. It is also compliant with RoHS standards and supports a long data retention period of up to 100 years, with a durability of 1,000,000 program/erase cycles.
