S524A40X10/40X20/40X40
1K/2K/4K-bit
Serial EEPROM for Low Power
with software write protect
Data Sheet
2-1
OVERVIEW
The S524A40X10/40X20/40X40 serial EEPROM has a 1,024/2,048/4,096-bit (128/256/512-byte) capacity,
supporting the standard I
2C™-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). 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
S524A40X10/40X20/40X40 is its support for fast mode and standard mode.
