S524AB0X91

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 I2C™-bus serial interface. It is fabricated using Samsung’ s 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.
