Overview
The CAT24C512XIT2 is a 512 kb Serial CMOS EEPROM produced by onsemi. This device is internally organized as 65,536 words of 8 bits each, providing a total memory size of 512 kb. It supports the I2C protocol with Standard (100 kHz), Fast (400 kHz), and Fast-Plus (1 MHz) modes. The EEPROM features a 128-byte page write buffer and includes hardware write protection to inhibit all write operations when the WP pin is pulled high. It is designed for high reliability applications with on-chip ECC (Error Correction Code) and operates within a supply voltage range of 1.8 V to 5.5 V.
