CAT24C32WI-GT3 Description

Short technical summary and product information.

The CAT24C32WI-GT3 from ON Semiconductor is a 32-kilobit serial EEPROM organized as 4096 words of 8 bits each. It supports the I2C protocol, including Standard (100 kHz), Fast (400 kHz), and Fast-Plus (1 MHz) modes.

This EEPROM features a 32-byte page write buffer and operates within a wide supply voltage range of 1.7V to 5.5V. The device is designed for industrial and extended temperature ranges, from -40°C to 85°C.

Available in an 8-SOIC package, the CAT24C32WI-GT3 is suitable for surface mount applications. It offers robust performance with 1,000,000 program/erase cycles and 100 years of data retention. The device also includes hardware write protection for the entire memory and Schmitt triggers with noise suppression filters on I2C bus inputs.

This component is Pb-free, Halogen Free/BFR Free, and RoHS compliant, making it suitable for environmentally conscious designs.
