Serial EEPROM
Data Sheet
OVERVIEW
The S524LB0D91/B0DB1 serial EEPROM has a 32/64 Kbits (4,096/8,192 bytes) capacity, supporting the
standard I²C™-bus serial interface. It is fabricated using Samsungs’ most advanced CMOS technology. One of
its major features is a hardware-based write protection circuit for the entire memory area. Hardware-based write
protection is controlled by the state of the write-protect (WP) pin. Using one-page write mode, you can load up to
32 bytes of data into the EEPROM in a single write operation. Another significant feature of the
S524LB0D91/B0DB1 is its support for fast mode and standard mode.
