Description and Introduction

256 x 8-bit CMOS EEPROMS with I2C-bus interface The **PCF8582E-2P** is a versatile **I²C-bus compatible** serial **EEPROM (Electrically Erasable Programmable Read-Only Memory)** integrated circuit designed for low-power, non-volatile data storage applications. Manufactured in a compact **DIP-8** package, this component provides **256 bytes of memory**, making it suitable for storing configuration settings, calibration data, or small datasets in embedded systems.  

Featuring a **two-wire I²C interface**, the PCF8582E-2P ensures easy integration with microcontrollers and other digital devices while minimizing board space and wiring complexity. It operates across a **wide voltage range (2.5V to 6V)**, supporting compatibility with various logic levels. Additionally, its **low standby current** makes it ideal for battery-powered applications where energy efficiency is critical.  

The device includes **built-in write protection** to prevent accidental data corruption and supports **sequential read operations** for efficient data retrieval. With a **100,000 write-cycle endurance** and **40-year data retention**, the PCF8582E-2P offers reliable long-term performance.  

Common applications include **industrial control systems, consumer electronics, and automotive modules** where small-scale, non-volatile memory is required. Its robust design and straightforward interface make it a practical choice for engineers seeking a dependable EEPROM solution.
