DESCRIPTION: The 24LC256 provides 256K bits of serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 32K words x 8 bits each. The device communicates via the I2C two-wire serial interface. The base I2C address is 0x50.If you need to do some data storage in your microcontroller, then using an EEPROM is probably the most simple way. In reality, microcontrollers have onboard EEPROM memory, but it is usually limited in capacity. This is an external EEPROM memory module which uses the I2C bus line to connect with Arduino, and with a pluggable chip, so it will be easy to expand capacity, you will have to just need to insert a bigger capacity of EEPROM chip if required.

EEPROM stands for electrically erasable programmable read-only memory. It is a non-volatile flash memory device, that is, stored information is retained when the power is removed. EEPROM generally offers excellent capabilities and performance. In EEPROM we can write and program the IC for many times and these are acting as EPROM (UV erasable programming ROM).

 This EEPROM Memory Module is based on AT24C256 IC which is I2C compatible chip. It has 256kb of memory in 32K*8 configuration.

Applicable for 

• EEPROMs are used in many applications such as telecom, consumer, automotive and industrial applications. The other applications include:
• Can be used to store device data like - Device ID, Cumulative Working Hours, Filter Life, Battery Charge/Discharge Cycsles, etc
• The reprogrammable calibration data for test equipment
• Data storage from a learn function as in a remote control transmitter.
• The device is optimized for use in consumer, industrial, and automotive applications where reliable and dependable nonvolatile memory storage is essential.
