1K/2K/4K/8K/16K-bit
Serial EEPROM for Low Power
Data Sheet
OVERVIEW
The S524A40X11/40X21/40X41/60X81/60X51 serial EEPROM has a 1,024/2,048/4,096/8,192/16,384-bit
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
16 bytes of data into the EEPROM in a single write operation. Another significant feature of the
S524A40X11/40X21/40X41/60X81/60X51 is its support for fast mode and standard mode.

S524A40X11/40X21/40X41/60X81/60X51 SERIAL EEPROM
FUNCTION DESCRIPTION
I2C-BUS INTERFACE
The S524A40X11/40X21/40X41/60X81/60X51 supports the I2C-bus serial interface data transmission protocol.
The two-wire bus consists of a serial data line (SDA) and a serial clock line (SCL). The SDA and the SCL lines
must be connected to VCC by a pull-up resistor that is located somewhere on the bus.
Any device that puts data onto the bus is defined as the “transmitter” and any device that gets data from the bus
is the “receiver.” The bus is controlled by a master device which generates the serial clock and start/stop
conditions, controlling bus access. Using the A0, A1, and A2 input pins, up to eight S524A40X11/40X21 (four
S524A40X41, two for S524A60X81, one for S524A60X51) devices can be connected to the same I2C-bus as
slaves (see Figure 1-6). Both the master and slaves can operate as transmitter or receiver, but the master device
determines which bus operating mode would be active.
