CAT24C512 EEPROM Memory Datasheet, Features, Pinout, and Applications

The CAT24C512 is a 512-kilobit (64 KB) electrically erasable programmable read-only memory (EEPROM) IC from ON Semiconductor. This serial EEPROM is designed for non-volatile data storage, offering a reliable and efficient solution for applications requiring frequent write and read cycles. With its I²C-compatible interface and robust memory performance, the CAT24C512 is ideal for consumer electronics, industrial systems, and automotive applications.

Overview of CAT24C512

The CAT24C512 represents a sophisticated EEPROM solution featuring a serial 512-Kb I2C architecture, methodically organized into 65,536 words, each comprising 8 bits. It boasts a 128-byte page write buffer, accommodating a range of I2C protocols, including Standard (100 kHz), Fast (400 kHz), and Fast-Plus (1 MHz) speeds. To safeguard data, write operations can be disabled by setting the WP (Write Protect) pin high, effectively securing the entire memory array. Additionally, the device supports addressing up to eight CAT24C512 units on the same bus through external address pins. Its integration of On-Chip ECC (Error Correction Code) renders it particularly reliable for high-stakes applications.
