The NV24C256 is a EEPROM Serial 256-Kb I2C - Automotive Grade, internally organized as 32,768 words of 8 bits each. It features a 64-byte page write buffer and supports both the Standard (100 kHz), Fast (400 kHz) and Fast-Plus (1 MHz) I2C protocol. Write operations can be inhibited by taking the WP pin High (this protects the entire memory). On-Chip ECC (Error Correction Code) makes the device suitable for high reliability applications.
