Description and Introduction

256 x 8-bit CMOS EEPROM with I2C-bus interface The **PCF8582C-2T** is a versatile **I²C-bus compatible** serial **EEPROM (Electrically Erasable Programmable Read-Only Memory)** designed for low-power, non-volatile data storage applications. With a capacity of **256 bytes (2 Kbit)**, this component is well-suited for storing configuration settings, calibration data, or small datasets in embedded systems, consumer electronics, and industrial devices.  

Featuring a **wide operating voltage range (2.5V to 6V)**, the PCF8582C-2T ensures reliable performance across various power conditions. Its **low standby current** makes it ideal for battery-powered applications where energy efficiency is critical. The device supports **byte-wise and page-wise write operations**, enabling flexible data management while maintaining fast access times.  

The **I²C interface** simplifies integration with microcontrollers and other digital systems, requiring only two bidirectional lines (SDA and SCL) for communication. Additionally, the PCF8582C-2T includes a **write-protect pin (WP)** to safeguard stored data against accidental modifications.  

Housed in an **8-pin SO package**, this EEPROM offers a compact footprint for space-constrained designs. Its robust architecture ensures **high endurance (1 million write cycles)** and **data retention of up to 40 years**, making it a dependable choice for long-term storage solutions.  

The PCF8582C-2T is widely used in applications such as smart meters, IoT devices, and automotive systems, where reliable, low-power memory is essential.
