CAT24C512 Serial 512Kb EEPROM IC – I2C – SOIC-8 – ON Semiconductor

The CAT24C512 is a high-reliability 512Kb (64KB) serial EEPROM from ON Semiconductor, featuring an I2C interface and organized as 65,536 × 8-bit memory cells. Operating across a wide 1.8V to 5.5V supply range, this EEPROM supports Standard (100 kHz), Fast (400 kHz), and Fast-Plus (1 MHz) I2C protocols, making it ideal for microcontroller-based data storage and configuration applications.

With a 128-byte page write buffer, the CAT24C512 enables efficient block writes and optimal performance in embedded systems. Hardware write protection via the WP pin secures the entire memory against unintended writes, while on-chip ECC (Error Correction Code) enhances data integrity for mission-critical applications.

Designed using low-power CMOS technology, this EEPROM supports 1,000,000 program/erase cycles, 100-year data retention, and is suitable for industrial and extended-temperature environments. External address pins allow up to eight devices on the same I2C bus. Packaged in a compact SOIC-8, it integrates easily into a variety of designs.
