The CAT1027LI-25-G is a dual voltage supervisory circuit designed for microcontroller-based systems, integrating a 2k-bit CMOS EEPROM with a power supply voltage monitor. It supports 5 V, 3.3 V, and 3 V systems with five selectable reset threshold voltage options, and features an auxiliary voltage monitoring capability adjustable down to 1.25 V. The device operates within a voltage range of 2.7 V to 5.5 V and utilizes a 400 kHz I¬=C bus for memory interfacing. This part includes a watchdog timer that resets the system if it becomes unresponsive, and offers both active high and low reset outputs, ensuring compatibility with various microcontrollers. The CAT1027LI-25-G is available in multiple package types, including 8-pin DIP, SOIC, TSSOP, MSOP, and TDFN, with the TDFN package having a maximum height of 0.8 mm. It is suitable for industrial applications, operating within a temperature range of -40¬?C to 125¬?C, and features a long data retention capability of up to 100 years.
