onsemi Supervisors CAT1640YI-42-T3

The CAT1640YI-42-T3 is a supervisory circuit designed for microcontroller-based systems, integrating a 64kbit serial EEPROM memory with a precision power supply voltage monitor. It operates within a voltage range of 3.0V to 5.5V and supports multiple reset threshold voltages, specifically tailored for 5V, 3.3V, and 3V systems. The device features an active low reset output, ensuring that the RESET signal is asserted when the supply voltage falls below the specified threshold, thus protecting the system during power fluctuations. This product utilizes a 400kHz I¬=C bus for memory interfacing and includes a 64-byte page write buffer, allowing for efficient data handling. It is built using low power CMOS technology, ensuring minimal power consumption, and offers a high endurance of 1,000,000 program/erase cycles with a data retention capability of up to 100 years. The CAT1640YI-42-T3 is available in various package options, including an 8-pin TSSOP, making it suitable for compact designs. The device operates within an industrial temperature range of -40¬8C to 85¬8C, ensuring reliability in diverse environments.
