The N24S64 is a 64 Kb Serial CMOS EEPROM, internallyorganized as 8,192 words of 8 bits each.They feature a 32-byte page write buffer and support both theStandard (100 kHz), Fast (400 kHz) and Fast-Plus (1 MHz) I2Cprotocol.The devices also feature a 128-bit factory-set read-only Unique ID,a 32-byte Secure Data Page that can be permanently locked againstfuture changes, and Software Write Protection of the entire array.A Device Configuration Register enables the user to specify the last3 bits of the Device Address, allowing up to eight N24S64 devices tobe addressed on the same bus.
