Description and Introduction
256 x 8-bit CMOS EEPROMS with I2C-bus interface The **PCF8582E-2** is a versatile **I²C-bus compatible** **256 x 8-bit EEPROM** with an integrated **real-time clock (RTC)**, designed for low-power applications. This component combines non-volatile memory storage with precise timing functionality, making it ideal for embedded systems requiring data logging, event timestamping, or configuration storage.  
Featuring a **256-byte EEPROM array**, the PCF8582E-2 supports **byte-wise and page-wise writing**, ensuring efficient data handling. The integrated RTC provides **seconds, minutes, hours, day, date, month, and year** functions, with automatic leap-year correction up to the year **2100**. Its **I²C interface** allows seamless communication with microcontrollers, reducing system complexity.   Operating at a **supply voltage range of 2.5V to 6V**, the PCF8582E-2 is suitable for both **battery-powered and mains-operated devices**. With **low standby current consumption**, it is optimized for energy-sensitive applications. Additionally, its **built-in write-protect feature** enhances data security by preventing accidental overwrites.   Common applications include **industrial automation, smart meters, medical devices, and consumer electronics** where reliable non-volatile memory and accurate timekeeping are essential. Its compact **8-pin DIP or SO package** ensures easy integration into various designs.   The PCF8582E-2 offers a balanced combination of **memory, timing, and power efficiency**, making it a practical choice for engineers seeking a multifunctional solution. |
