CAT24C512YI-GT3 – 512Kbit I2C EEPROM Memory IC, High Reliability, TSSOP-8 Package
The CAT24C512YI-GT3 is a high-performance 512-Kbit serial EEPROM memory IC designed for industrial and extended temperature applications. This device is internally organized as 65,536 words of 8 bits each, offering efficient memory management and superior endurance. It supports the Standard (100 kHz), Fast (400 kHz), and Fast-Plus (1 MHz) I2C protocols, providing flexible and fast communication options for a wide range of embedded systems. The EEPROM features an on-chip ECC (Error Correction Code) for data reliability, hardware write protection via the WP pin, and external address pins that enable up to eight devices to operate on the same bus. With 1,000,000 program/erase cycles, low power CMOS technology, and a 100-year data retention, this IC is ideal for applications requiring durability and data integrity such as industrial control, automotive systems, and consumer electronics.
