... Description The M24512-x devices are I (EEPROM). They are organized × 8 bits. The M24512-x can decode the type identifier code (1010) in accordance with the I definition. The M24512-DR also decodes the type identifier code (1011) when accessing the identification page. The M24512-DR offers an additional Identification Page (128 bytes) which can be written and (later) permanently locked in Read Only mode ...
