ON Semiconductor CAT24C512 512Kbit I2C Serial EEPROM, SOIC-8

The ON Semiconductor CAT24C512WI-GT3 is a high-performance 512Kbit CMOS Serial EEPROM, engineered for reliability and efficiency in demanding applications. Internally organised as 65,536 words of 8-bit each, this device features a 128-byte page write buffer for efficient data programming. It offers flexible compatibility by supporting the standard (100kHz), fast (400kHz), and fast-plus (1MHz) I²C communication protocols, allowing for integration into systems with varying speed requirements.

A key security feature is the hardware write protection, activated by taking the WP pin high, which safeguards the entire memory array from unintended writes. External address pins enable the connection of up to eight CAT24C512 devices on the same I²C bus, simplifying system design for expanded memory needs. The inclusion of on-chip Error Correction Code (ECC) significantly enhances data integrity, making this EEPROM suitable for high-reliability applications where data accuracy is critical.

Robust Design & Longevity

Engineered with low-power CMOS technology, the device is ideal for power-sensitive designs. It boasts an exceptional endurance rating of 1,000,000 program/erase cycles and a guaranteed data retention period of 100 years, ensuring long-term reliability. Additional robustness is provided by Schmitt triggers and noise suppression filters on the I²C bus inputs (SCL and SDA), ensuring stable communication in electrically noisy environments typical of industrial settings.
