Description
It features a hardware write-protect pin to safeguard data integrity by preventing accidental writes. The AT24C02BN-SH-T is organized in 32 pages of 8 bytes each, allowing for efficient data management. Its endurance rating is up to 1 million write cycles, and it retains data for over 100 years, ensuring long-term reliability. The device is typically available in a small outline Transistor Outline (SOT) package, making it suitable for space-constrained applications. With its low power consumption and robust performance, this EEPROM is ideal for consumer electronics, automotive, and industrial applications.
Equivalent
1. Microchip 24LC02B series
2. STMicroelectronics M24C02 series
3. ROHM BR24G02 series
4. ON Semiconductor CAT24C02 series
These alternatives typically share similar features like memory size, I2C interface, and operating voltage, but it's important to verify pin configuration and specific electrical characteristics to ensure compatibility.

Pinout
1. A0, A1, A2 (Pins 1, 2, 3): These are device address inputs used for multiple device addressing. They allow for up to eight devices on the same I²C bus.
2. VSS (Pin 4): Ground reference for the IC, connected to the system ground.
3. SDA (Pin 5): Serial Data Line, a bidirectional line for data transfer.
4. SCL (Pin 6): Serial Clock Line, used to synchronize data transfer between the microcontroller and the EEPROM.
5. WP (Pin 7): Write Protect input. When connected to VCC, it disables write operations to the memory, providing hardware write protection.
6. VCC (Pin 8): Power supply pin for the device, typically connected to a 1.7V to 5.5V supply.
The device operates on the I²C protocol, which allows for easy interfacing with microcontrollers. It is commonly used for storing small amounts of data requiring retention without power.
