S524A40X10/40X20/40X40
1K/2K/4K-bit
Serial EEPROM for Low Power
with software write protect
Data Sheet
OVERVIEW
The S524A40X10/40X20/40X40 serial EEPROM has a 1,024/2,048/4,096-bit (128/256/512-byte) capacity,
supporting the standard I2C™-bus serial interface. It is fabricated using Samsungs’ 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.

Input
Input pins for device address selection. To configure a device address,
these pins should be connected to the VCC or VSS of the device.
These pins are internally pulled down to VSS.
Ground pin.
Bi-directional data pin for the I2C-bus serial data interface. Schmitt
trigger input and open-drain output. An external pull-up resistor must
be connected to VCC. Typical values for this pull-up resistor are 4.7 k
(100 kHz) and 1 k(400 kHz).
Schmitt trigger input pin for serial clock input.
Input pin for hardware write protection control. If you tie this pin to VCC,
the write function is disabled to protect previously written data in the
entire memory; if you tie it to VSS, the write function is enabled.
This pin is internally pulled down to VSS.
Single power supply.
