CAT24C128WI-G Description

Short technical summary and product information.

The CAT24C128WI-G from ON Semiconductor is a 128Kbit serial EEPROM organized as 16,384 words of 8 bits each. It features a 64-byte page write buffer and supports the Standard (100 kHz), Fast (400 kHz), and Fast-Plus (1 MHz) I2C protocols.

 

This device operates within a wide supply voltage range of 1.8V to 5.5V, making it suitable for various applications. Key electrical characteristics include a maximum clock frequency of 1MHz and an access time of 400ns. The EEPROM offers 1,000,000 program/erase cycles and 100 years of data retention, ensuring reliability.

 

Designed for surface mounting, the CAT24C128WI-G comes in an 8-SOIC package with dimensions of 0.154 inches (3.90mm) width. It operates within an industrial and extended temperature range of -40°C to 85°C (TA).

 

Features such as on-chip ECC (Error Correction Code) and hardware write protection for the entire memory enhance its suitability for high-reliability applications. Schmitt triggers and noise suppression filters on the I2C bus inputs (SCL and SDA) contribute to robust communication.
