Overview

Description

The 24LC256-I/SN is a 256-kbit EEPROM (Electrically Erasable Programmable Read-Only Memory) device that uses I2C (Inter-Integrated Circuit) communication for interfacing with microcontrollers and other digital devices. It features a storage capacity of 32 kilobytes, organized as 256 pages of 128 bytes each.
Key characteristics include:
- Operating Voltage: Typically 1.7V to 5.5V.
- Data Retention: Can retain data for over 100 years under normal conditions.
- Write Cycles: Endurance of approximately 1 million write/erase cycles per memory cell.
- I2C Interface: Supports standard and fast modes, allowing multiple devices on the same bus with unique addresses.
- Page Write Capability: Allows writing data in pages, improving efficiency.
The 24LC256-I/SN is widely used in applications requiring non-volatile memory, such as data logging, configuration settings, and storing calibration data in embedded systems. Its compact size and ease of integration make it suitable for a variety of electronic projects.
