3. Operating Voltage: Wide range of 1.7V to 5.5V, suitable for various applications.
4. Low Power Consumption: Features low active and standby current for energy-efficient operation.
5. Write Protection: Includes a hardware write-protect pin to prevent accidental data overwrites.
6. Endurance: High endurance with 1 million erase/write cycles and a data retention lifespan of over 200 years.
7. Package Options: Available in 8-Pin SOIC (Small Outline Integrated Circuit) package.
8. Temperature Range: Operates across an extended temperature range, making it suitable for industrial applications.
These features make the 24LC256-E/SN ideal for data logging, configuration storage, and other applications requiring reliable, non-volatile memory.
Pinout
1. A0, A1, A2: These are device address inputs used for determining the I2C address of the EEPROM. They allow for up to 8 devices on the same bus.
2. VSS: Ground reference for the device.
3. SDA (Serial Data): This is the data line for both input and output in I2C communication.
4. SCL (Serial Clock): This is the clock line for I2C communication.
5. WP (Write Protect): This pin is used to enable or disable write operations to the EEPROM. When tied to VCC, write operations are inhibited.
6. VCC: Supply voltage for the device.
This EEPROM is often used in applications requiring non-volatile storage with a simple I2C interface, such as configuration data storage in embedded systems.
