Description



The BL24C64A provides 65536 bits of serial

electrically erasable and programmable read-

only memory (EEPROM), organized as 8192

words of 8 bits each.



The device is optimized for use in many

industrial and commercial applications where

low-power and low-voltage operation are

essential.



The BL24C64A offers an additional page,

named the Identification Page (32 bytes). The

Identification Page can be used to store

sensitive application parameters which can be

(later) permanently locked in Read-only mode.
