onsemi Supervisors CAT1641YI-30-GT3

The CAT1641YI-30-GT3 is a supervisory circuit that integrates a 64 kbit serial EEPROM memory with a power supply supervisor, designed for microcontroller-based systems. It operates within a voltage range of 3.0 V to 5.5 V and features a 400 kHz I2C bus interface for memory access. The device provides an active high reset output, ensuring that the system is reset when the supply voltage falls below a specified threshold. It supports multiple reset threshold options suitable for 5 V, 3.3 V, and 3 V systems, with valid reset guaranteed at VCC levels as low as 1 V. The CAT1641YI-30-GT3 includes hardware data protection that prevents memory writes during power fluctuations, enhancing system reliability. It is available in various package types, including an 8-pin TSSOP, and is suitable for industrial applications with an operating temperature range of -40¬8C to 85¬8C. The product is compliant with RoHS standards, making it a suitable choice for environmentally conscious designs.
