CAT1023WI-30-GT3 Description

Short technical summary and product information.

The CAT1023WI-30-GT3 from ON Semiconductor is a supervisory circuit integrated with a 2k-bit I2C EEPROM memory. This component is designed to provide complete memory and supervisory solutions for microcontroller-based systems. It features a precision VCC sense circuit and open drain outputs that activate when VCC falls below a set threshold voltage.

 

The supervisory functions include a watchdog timer with a 1.6-second timeout to reset the system if it halts or hangs, and a manual reset input for push-button capability. The power supply monitor and reset circuit protect memory and system controllers during power up/down and brownout conditions. It supports 3V systems with a 3V threshold voltage.

 

This device operates via a 400 kHz I2C bus and is housed in an 8-SOIC package suitable for surface mounting. The operating temperature range is -40°C to 85°C. The CAT1023WI-30-GT3 is manufactured using low power CMOS technology and offers features like a 16-byte page write buffer and built-in inadvertent write protection.
