EEPROM Data Storage AT24C256

The OKY3417-1 is a non-volatile EEPROM memory module, built around the AT24C256 IC, providing 256 Kbit of reliable data storage that persists even without power. It is designed for easy integration with microcontroller systems for storing configuration data, logs, or other essential information.

Key Features
- Features a 256 Kbit memory capacity, organized as 32,768 words of 8 bits each.
- Utilizes the standard I2C two-wire serial interface for straightforward communication with host devices.
- Supports cascading, allowing up to eight modules to be connected to a single I2C bus to expand total storage capacity.
- Offers a wide operating voltage range from 1.7V to 5.5V, ensuring compatibility with both 3.3V and 5V logic systems.

Applications
This module is ideal for projects requiring persistent data logging or configuration storage with microcontrollers. Its standard I2C interface and broad voltage compatibility make it a versatile choice for use with platforms like Arduino, where data must be retained after power cycles.
