Features
1. Capacity: 256 Kbit organized as 32,768 x 8 bits.
2. Interface: I2C bus, supporting standard (100 kHz), fast (400 kHz), and fast-plus (1 MHz) modes.
3. Voltage Range: Operates in a wide voltage range from 1.7V to 5.5V.
4. Low Power Consumption: Consumes minimal power, with typical read current at 400 µA and standby current at 1 µA.
5. Data Retention: Offers over 200 years of data retention.
6. Endurance: Up to 1 million erase/write cycles per byte.
7. Page Write: Supports a page write of up to 64 bytes.
8. Temperature Range: Functions in industrial temperature ranges from -40°C to +125°C.
9. Package: Available in an 8-pin MSOP package.
10. Write Protection: Includes a write-protect pin to safeguard data integrity.
These features make it suitable for a wide range of applications requiring reliable non-volatile memory storage.
Pinout
1. A0, A1, A2: These are address pins used for device selection, allowing up to eight devices on the same bus by changing the combination of these pins.
2. VSS: Ground pin.
3. SDA (Serial Data): This pin is used for data input/output. It is a bidirectional line for reading and writing data.
4. SCL (Serial Clock): This pin is used to synchronize the transfer of data.
5. WP (Write Protect): This pin is used to enable or disable write operations. When connected to VCC, write operations are inhibited.
6. VCC: Power supply pin.
This EEPROM operates on an I2C interface, which allows for simple two-wire communication between devices. It is commonly used for applications requiring non-volatile data storage without power, such as configuration data, user settings, or system calibration data.
