Overview
The CAT24C512C8UTR is a 512 Kb Serial CMOS EEPROM produced by onsemi. It is internally organized as 65,536 words of 8 bits each, providing a total storage capacity of 512 Kb. This device supports the Standard (100 kHz), Fast (400 kHz), and Fast-Plus (1 MHz) I2C protocol, making it versatile for various applications. The CAT24C512C8UTR features a 128-byte page write buffer and includes hardware write protection for the entire memory, which can be activated by taking the WP pin High. It also includes on-chip ECC (Error Correction Code) for high reliability applications and supports addressing up to eight devices on the same bus using external address pins.
