S524AB0X91/B0XB1
32K/64K-bit
Serial EEPROM
for Low Power
Data Sheet
OVERVIEW
The S524AB0X91/B0XB1 serial EEPROM has a 32K/64K-bit (4,096/8,192 bytes) capacity, supporting the
standard I2Câ¢-bus serial interface. It is fabricated using Samsungsâ most advanced CMOS technology. It has
been developed for low power and low voltage applications (1.8 V to 5.5 V). One of its major feature 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 S524AB0X91/B0XB1 is its support for
fast mode and standard mode.
