Serial EEPROM
with software write protect
Data Sheet
OVERVIEW
The S524C20D10/20D20/80D40/80D80 serial EEPROM has a 1,024/2,048/4,096/8,192-bit (128/256/512/1,024-
byte) capacity, supporting the standard I2C™-bus serial interface. It is fabricated using Samsungs’ most
advanced CMOS technology. Important features are a hardware-based write protection circuit for the entire
memory area and software-based write protection logic for the lower 128 bytes. Hardware-based write protection
is controlled by the state of the write-protect (WP) pin. The software-based method is one-time programmable
and permanent. Using one-page write mode, you can load up to 16 bytes of data into the EEPROM in a single
write operation. Another significant feature of the S524C20D10/20D20/80D40/80D80 is its support for fast mode
and standard mode.
